Eisenia fetida (red wigglers) keeping - pets or livestock? How do you feel about yours?
How do people feel about their compost worms? I jokingly refer to mine as pets but I am kind of attached to them in aggregate so maybe mostly serious. I don't 'pet' them but I do like checking on them and watching them. On the other hand, they are not companion animals like my cat. They break down my veggies for me.

Help! Centipedes and beneficial bugs
Hey everyone, I hope this is sub-appropriate. I have a few questions I can't find answers to.
I just found centipedes (specifically Lithobius Forficatus) in the soil of one of my carnivorous plants.
- Will they take a noticeable amount of food away from the plant?
- Do they eat the same food as a carnivorous plant?
- Will they eat fungus gnats/larvae or spider mites?
- Will they eat beneficials? I have Lacewings and just applied Californicus larvae.
- Would the actuality of centipedes in my plants suggest the soil and/or (specifically is it "and" or, "or"?) plants are healthy? Or does this not suggest either?
- IE: Bacterial/fungal infection free? Do centipedes not give a fuck?
Thank you so much for taking the time to read this, lol.

Hello entomologist HELP please
I have no background about the insects and my doctor asked me to present a beneficial insect or insect with special role. She asked about a new discovered or un-known insects. So please share me any information could help my presentation.
Thank you

Mantis hanging upside down problems
Hey guys my sub adult ghost is due a molt any day now but she seems very week and keeps falling from her perch several times and can’t seem to stay hanging upside down for more than a few mins. Should I just tape her back legs to a twig before her moult so at least she won’t fall during?

Melolontha sp. I just found (Escarabajo Sanjuanero). I'm doing an entomology collection for my zoology class in university, extra credit. We haven't gotten to how to preserve and properly pin the insects, should I freeze it in the mean time?
How to preserve bugs
I like to preserve (already dead) bugs that I find, I found a moth in my curtain that had passed, and I’m wondering what liquid I can use to preserve them in jars? I heard rubbing alcohol but wouldn’t that dissolve the big? I’ve tried hand sanitizer on smaller specimens but it creates a jelly like like substance around the bug. Thanks for the help!

I got this shot of an Emerald/Cuckoo Wasp (Chrysididae) with a picture-winged fly of some sort last summer hanging out on my black-eyed pea stalks. Gorgeous coloring!
I study termites, AMA; I think their biology is super under appreciated. Here’s a photo I took of a pacific dampwood termite (Zootermopsis angusticollis) soldier. They can’t eat with these big mandibles, so they rely on anus-to-mouth or mouth-to-mouth gut fluid exchange from workers.

Booklice: The Cutest of Pests | Catalogue of Organisms
Humans have a tendency to think of 'nature' and the 'environment' as something distinct from our own society. Environments unmodified by humans are seen as 'natural' whereas structures created by human activity, such as buildings, are not 'natural' and thought to be somehow outside the 'environment'. As such, people often react strongly to the idea of things associated with the 'environment', such as non-human wildlife, encroaching on their homes. But of course, human houses are as much an environment of their own as any other of the world's habitats, and many animals find them to be places where they can thrive. Among the animals that most regularly share our houses with us are booklice of the genus Liposcelis.
Liposcelis bostrychophila, copyright Andreas Eichler.
Representatives of Liposcelis can be found almost anywhere in the world except in the coldest of regions. About 130 species have been described in the genus to date (Yoshizawa & Lienhard 2010) with doubtless more yet to be discovered (by comparison, Broadhead's review of the genus in 1950 recognised only 22 species, with a six-fold increase since then). The family Liposcelididae, to which Liposcelis belongs, differ from other free-living members of the Psocodea (or 'Psocoptera') in their flattened body form, as well as being smaller than most other examples (Liposcelis grow little more than a millimetre in length). In the flattened habitus, they resemble the parasitic true lice of the Phthiraptera, and recent studies have agreed that the liposcelidids represent the closest relatives of true lice (Yoshizawa & Lienhard 2010). Liposcelis species are readily distinguished from other liposcelidids by the shape of the hind legs: an obtuse tubercle on the outer margin of the hind femur gives it a distinctly broad appearance* (indeed, the genus name Liposcelis translates into English as 'fat thigh'). Liposcelis are also distinctive in being invariably wingless; other liposcelidid species typically come in both winged and wingless forms. Though the genus as a whole is easily recognised, distinguishing individual species is often a far more challenging prospect requiring microscopic examination of fine features of the chaetotaxy (arrangement of bristles on the body) and cuticular sculpture. Authors have divided Liposcelis species between a number of diagnostic sections and subgroups based on these and other features but the monophyly or otherwise of these subdivisions is largely unstudied.
*This feature is also shared with a cave-dwelling species from Ascension Island currently placed in its own genus, Troglotroctes ashmoleorum, but it seems more than likely that this species is itself a derived offshoot of Liposcelis.
Liposcelis species can feed on a wide range of organic matter but, like other 'Psocoptera', their primary source of food is probably yeasts and fungal spores (their vernacular name has been attributed to their feeding on yeasts growing on the glue binding books, though I would note that they are also probably more likely to be seen crawling on the light background of a book's page than in other, less closely examined corners of the house). Turner (1994) provided a detailed review of the natural history of one of the most widespread domestic pest species in the genus, L. bostrychophila, and reports that he was able to maintain cultures on "'Weetabix'™, 'Shreddies'™, baby rice, soya granules, sage and onion stuffing mix, skimmed milk powder, 'Oat Krunchies'™, red lentils, and yellow split peas". Other stored foods from which complaints had been received of booklice included "sugar, bread, salt, bay leaves, gelatine powder, poppadoms, custard powder, dried yeast, instant potato, nuts, dried fruit, baby food, sauce mix, dried mushrooms, pasta, coconut, cocoa, milk powder, spices, glace cherries, garlic, baking powder, icecream mix, dried soup, cracked wheat, carob powder, maize meal, wheat germ, jellied sweets and bread crumbs". They have also been found on cured meat and may damage curated insect specimens. As well as obtaining moisture from their food, Liposcelis are also able to extract water directly from the atmosphere owing to the hygroscopic properties of their saliva. A booklouse will hold a drop of saliva inside its mouth, then swallow it when the ball has absorved enough water from the air.
Liposcelis sp. (possibly L. meridionalis?) from southern France, copyright Jessica Joachim.
Female Liposcelis bostrychophila generally reach maturity and begin producing eggs about two weeks after hatching and may produce two or three eggs a day. As each egg is about one-third the size of the adult, this means that a female at peak fecundity is producing her own body mass in eggs in a single day. Most Liposcelis species reproduce sexually but some are parthenogenetic. Domestic L. bostrychophila, for instance, seem to be entirely parthenogenetic with males of the species only known from isolated collections in Hawaii, Arizona and Senegal (Georgiev et al. 2020). Studies on an unnamed species of Liposcelis from Arizona found that sex determination seemed to be facultative, determined by the mother, with no evidence for differentiated sex chromosomes (Hodson et al. 2017). Females seemed to produce more males early in life and more females later. The same studies also established the occurrence of paternal genome elimination in this species, where chromosomes inherited from the father were inactivated in the offspring and not passed on to their own progeny (which raises the question that, if males are effectively a genetic dead end, why would a female produce male offspring at all?) Paternal genome elimination has also been found in the human louse Pediculus humanus, and may be characteristic of the broader clade encompassing these species, but other species remain unstudied. Liposcelis genomes are also remarkable in the occurrence of fragmentation of the mitochondrial genome. Whereas some Liposcelis species have only a single mitochondrial chromosome, as is standard for most other animals, some species have the mitochondrial genome divided between two, three, five or seven chromosomes (Feng et al. 2019). The functional significance, if any, of this feature remains unknown.
Though booklice may be found in houses and stores on the regular, they are mostly only minor pests, only causing distress when reaching large numbers (an exceptional case quoted by Turner, 1994, involved a house in New Jersey at the beginning of the 1900s that became so infested "'that a pinpoint could not have been put down without touching one or more of these bugs"). They are not believed to transmit pathogens, except perhaps incidentally by carrying microbes from one store to another. For the most part, these little beasties are just another part of the wildlife that shares our homes with us, whether we are aware of them or not.

I don't know how I've lived so long not looking at a dragonfly face but today I finally saw their ocelli and am...kind of horrified and cannot unsee them as tiny terrifying eyeballs spaced perfectly throughout the middle of their face.
I needed to share this gorgeous creature. Giant ichneuman wasp, ~5 inches from the head to the tip of the ovipositor. Seen last summer in southern Maine.
Good day, my little brother and i stumbled upon this funny looking fellow today. Might anyone help us identify it? The picture was taken in Suriname if that helps.
What are these? Small black beetles found swimming very quickly in a FREEZING creek. Ambient temp was mid teens (f). They were active all night. When I got up at 5 am they were still very active. I had no idea there would be surface aquatic insects feeding in late January in northern LP Michigan.
Question about insect DNA.
Do all insects that have the same sex and belong to the same species have the same DNA molecules?
I'm asking this question because we (well I) can't see any difference between female black widows or 2 female mosquitos that belong to the same species.

Resources for an aspiring young forensic entomologist?
I have a daughter in upper elementary school who has a deep love of insects and has wanted to be an entomologist since age 5. She recently discovered forensic entomology and thinks this is the specific career she would like to pursue. I know she is still young and many things could change but does anyone know of a good book or other resources that could help her learn about this area of study and explore the field more? She did take the University of Alberta Bugs 101 course through Coursera and loved it. (This is where she learned about forensic entomology).
We have joined local entomology groups, raise insects like hissing cockroaches and millipedes, watch documentaries, etc to support her passion but other thoughts on great resources for kids about entomology in general are always appreciated too.!
Edited: to correct to University of Alberta

Sapient Cockroackes speculative evolution
U am writing up a spec evo about cockroaches gaining sentience after mass extinction of most land vertebrates. I would appreciate feedback, especially from people who study or are interested in entomology, which is why I posted it here in addition to the spec evo sub.
This takes place in a timeline where Nuclear Armageddon happened, leaving much of the northern hemisphere a desolate nuclear wasteland, with the remainder humans plagued by famines, war, and drastic changes in temperature. In addition most other vertebrate species perish due to the radiation and weather changes. Another extinction event like an asteroid hitting the Earth could also happen, cementing the mass extinction of land vertebrates.
The world now belongs exclusively to the arthropods who managed to survive thanks to their exoskeleton and small size.
After several millions of years insects began to evolve and fill the niches of the previous vertebrates, many convergently evolving similar body plans. In particular a clade of Cockroach has gained sapience that is comparable to that of humans thanks to some lucky adaptations.
Why cockroaches? Well for starters they’re known to survive high doses of radiation (Although generally less than many other arthropods). I also personally think they’re neat. But the main reason is that there are several species of Cockroach that exhibit prolonged care for their young. It is very rare for insects to take care of their young, as most are r-selected species, but a few species of cockroach are the exception. The most notable are roaches of the genus Cryptocercus which raise 20 nymphs for 3 or more years (more than many mammals). The adults feed the young through Trophallaxis. The Australian giant burrowing cockroach (Macropanesthia rhinoceros) also takes care of its young for about six months. There is even a species of Cockroach (Perisphaerus) where the mother suckles their young. Cockroaches evolved as an Ootheca, with some even giving live birth.
Overall these cockroaches are the most social insects that aren’t eusocial, and brood care is essential for the majority of species that gain sapience (the octopus being an exception) and necessary to create a civilization.
So let’s take a look at the evolution of our buggy friends
Lungs and Closed Circulatory System
Without any predators, these cockroaches will be able to get bigger as they can consume resources freely. However, their body size is limited thanks to the insect’s spiracles, which are a highly inefficient way of getting oxygen, as well as the fact they have an open circulatory system.
As time goes by, some cockroaches select for stronger muscles at the spiracles which are able to take in more oxygen. As time goes on the Spiracles brachiate forming mini “lungs' ' on the cockroache’s abdomen. In addition, the cockroach gains a closed circulatory system, with their heart pumping blood to the rest of their body. The closed circulatory system has convergently evolved in several invertebrates like worms and cephalopods which is how it happened here. Hemoglobin is also found in some insect species and is a much more efficient way of transporting oxygen, so our roach friends gain this as well.
Their size will still be limited by their exoskeleton, and unless the somehow evolve an internal skeleton they probably won’t be much larger than a coconut crab. I’m not sure how likely it would be for an arthropod to evolve an internal skeleton.
Anyways at this point the roaches’ superior respiratory and circulatory system will allow it to excel further, although it is possible other arthropods will evolve similar structures. I shall be focusing on one particular species of roach even though they will likely be thousands of members in this clade.
Endothermy and Homeothermy
As the Roach gains a larger size and more advanced circulatory system they will also develop the ability to internally regulate their temperature. Their circulatory system can move their blood around. Their antennae also might become feather-like similar to moths, where the increased surface area can help them cool down.
Dexterous hands and forearms
Picking up and carrying things back to one’s nest can be advantageous to the cockroach. Thus several roaches evolved a body similar to a praying mantis (Which has happened before in the extinct cockroach species Manipulator modificaputis). Although specialized in grabbing and carrying things rather than hunting. It is possible they end up living in trees and adopt a diet of nuts and fruit. They also might use their forearms to swing on branches like a monkey.
Vocalization
The cockroach is not alone in this world, and there are many predators like other roaches but others might include wasps, spiders, scorpions, centipedes, and giant crabs. It is possible that many of them co-evolved similar traits allowing them to get larger sizes. (It is also possible that several small species of land vertebrates survived the extinction although lived mostly underground as the world was irradiated and are just now resurfacing.)
While roaches and other insects today communicate through pheromones, sound moves faster than chemicals in air, meaning if the community of roaches are to evade predator attacks, the ability to vocalize will be useful. Madagascar hissing cockroaches have the ability to “hiss” through their spiracles, and since the spiracles for the future roaches .
Their spiracles will gain an organ allowing them to make loud and complex noises, similar to the syrinx of a parrot. This vocalization will also make it more useful to get food and teach their young. They will likely still use pheromones, but rather than complex communication it might be to show their emotions, not unlike body language humans do. As the roaches have exoskeletons they have less facial movements so they can use pheremones sho show their emotion.
Enlarged Brain
Of course the final step of sapience is the requirement for an enlarged brain. As the roach gains a better circulatory system, better ability to gather resources, and the ability to communicate, a large brain that requires a lot of calories can be created. Cockroaches currently have 1 million brain cells, which is rather pitiful, but on the higher end for insects.
As their brains get larger the instincts that drive them to brood care and forming social colonies become more complex into genuine emotions of love and kindness, thus creating stronger social bonds.
Despite being intelligent they will be very different than humans. Perhaps their social bonds will be even stronger, allowing them to form large civilizations with less tribalism.
There are generally 4 checkmarks for an advanced civilization to develop:
Social group Tool use Discovery of Fire Agriculture
Currently, cockroaches are already rather social insects that live in groups, and with more brood care already check that off.
Since the roaches in this timeline have “hands” they are capable of using tools. They will likely start off with crushing nuts with rocks but might form more complex tools as time goes by. Including being able to create fire through rubbing sticks.
As for agriculture, that has already been discovered by some species of termites and ants. In this radioactive world it is possible that radiotrophic fungi have filled the niche of many plants (And are using UV radiation from the sun when the radiation from the nukes ran out) and the roaches grow fungi like their termite cousins. Or simply grow plants.

Saw a pantry moth - first one in 6 months, I used to have an infestation. Are they back?
So at my old apartment, the infestation was bad. Like you’d walk into a room and see a dozen on the ceiling and several more on the walls. Was like this for months, despite multiple traps that would collect 50+ (estimating). When I moved, they mostly didn’t come with me. I saw maybe a total of 5 or 6 my first month living here (June 2020), and haven’t seen a single one since then. Until yesterday. I saw one. Killed it immediately. But what does this mean? Are they back? How and why was there such a long period without them?
Edit to add: I just remembered that the 5 or 6 I mentioned were ones I killed on the walls/ceiling. I had a trap set up as soon as I got here and I think it caught like 6 or 7. So total there were like a dozen moths here in June, but I haven’t seen any since then.
Edit 2: I am reposting in hopes that people see the post this time. Thank you!
