Can anyone ID this Apidius species?
 |
These came in with the aphids this year.. NE Wisconsin, North America. Trying to ID to species or find a species list/desc for the locally occurring ones here. This one is shown on a 24mm wide strip.. Most are in the 3-4mm range, with some falling short of 2mm and some maybe over 5mm. I don't handle them much, but have a couple of dead specimens if I know what I'm looking for. [link] [comments] |

Jerusalem Cricket Infestation
I moved into a new home on the coast of Southern California a few months ago. Lately we’ve been getting these big ass Jerusalem crickets that just keep finding their way inside. We set up bug traps and capture like 2-3 of them every time. They’re fucking huge too. They’ve already tried biting all my family lmao. Fucking hell they lunge at you and try to bite. As someone who had a phobia of spiders, in actually having a really hard time dealing with this. Like I don’t even want to live in this neighborhood, it’s getting that bad. I’ve tried looking up dozens of posts for getting rid of them but I can’t get any solid advice. Do I call pest control to come get rid of all this ?

Needed help with pinning bug for the first time (and identifying it)
 |
Hi! I need help identifying a bug and most of all - pinning it (never done it before and I feel like every website says something different). Hopefully I'm in the right place :) In the beginning of July I went on a vacation to southern Poland (near Ząbkowice) and everyday I've seen this bug on my driveway - all these days he hadn't even moved a bit (well, he was dead). I decided to take him back home with me and pin it. And there is my question... It's been months since he died (the whole time he's been sitting in a paper box BUT upside down - it was easier to transport him by car this way without breaking his legs what happened anyway), I guess it's still possible to pin him since I've read he needs to be dry...? Please help me, I know nothing about pinning, I'm afraid to even pick him up because of the thought I could break him. How do I do it? Where do I get the needles (and I would prefer not to buy like 50 of them)? Do I prepare the bug somehow? I've bought an about 3,5-4 cm (1,37-1,57 inches) deep picture frame from IKEA, so hopefully the needle (and something - what? - I stick the needle in) would fit. Any help greatly appreciated :) (or at least links to reliable websites that would help in this case) [link] [comments] |

The Bolivinitids | Catalogue of Organisms
The Cretaceous was a period of significant innovation in the evolution of Foraminifera with a number of distinct new lineages making their appearance during this period. Among those, appearing in the latter part of the Cretaceous, were the first members of the modern family Bolivinitidae.
Bolivinita costifera, from the Smithsonian National Museum of Natural History.
The Bolivinitidae are free-living benthic forams with a calcareous, hyaline (glassy) test. The overall shape of the test is elongate with chambers arranged in biserial coils (that is, there are two chambers per loop). The terminal aperture is usually loop-shaped with a surrounding lip. Inside the chamber, a tooth plate (an inner protrusion of the test) runs from the aperture to the opening of the previous chamber and may protrude through the aperture (Revets 1996).
Representatives of the Bolivinitidae are found in a wide range of depths, from the shallow waters of the ocean to the bathyal zone. They may be among the most abundant forams in areas of low oxygen concentrations and are commonly associated with sustained organic matter input (Erdem & Schönfeld 2017). In other words, these are muck-lovers. Individuals growing in low oxygen conditions tend to show less pronounced surface sculpture on the test than those where the oxygen levels are higher. Conversely, individuals at deeper levels tend to be larger overall than those in shallower waters (Brun et al. 1984). As such, bolivinitids have received their fair share of attention as potential indicators of changes in environmental condition over time.

What bug is this? Recently I moved and found those tiny worms on my bathroom floor, my bed, on the floor near baseboard. I have no idea what they are, and what to do.
A Black Beatle

Took a picture of this beatle, and just feel really proud of how cool it looks. Wanted to share. Assuming it's just a black beatle? Let me know if it's something else. :) [link] [comments] |

WHAT is this!? The closest looking thing I could find on Google is a varied carpet beetle larvae, it was about, idk, I'm gonna go out on a limb and say 3mm long? Very small.

What’s this bug? Any info appreciated! Roughly 2mm long, found mainly in the kitchen and bathroom, usually 2-3 together, live in the PNW. Thank you kindly!
The gang’s all here! It’s the whole collection, only eight of which were not spread by me. The two glass backed cases, the Chinese moon moth, and the two female Dynastes centaurus were bought or found pre-spread. This is, of course, not counting the unspread specimens I have waiting.

Best moth identification guide? UK based
Hello!
Does anyone have any recommendations for a good identification book for the moths of UK/Europe? During my degree, we used brilliant ones during moth trapping exercises, that included life size illustrations in their resting states but now can't remember the book! Thank you!

Crossing the Busycon | Catalogue of Organisms
I must admit that when I think about the biodiversity hotspots of the world, the eastern seabord of the United States would not be among the first regions to come to mind. But for this post, I'm looking at a dramatic and eye-catching radiation of molluscs for which this is their centre of distribution. I speak of the giant whelks of the Busyconidae.
Left-handed whelk or lightning whelk Sinistrofulgur sinistrum, copyright Andrea Westmoreland.
Busyconid whelks first appeared in the waters of eastern North America during the early Oligocene, about 32 million years ago, in what was then the Mississippi Sea and is now the Mississippi River Basin. As the oceans receded from the Mississippi, they spread into the Gulf of Mexico and are now found between Massachusetts in the north and the Yucatan Peninsula in the south. Except for an introduced population of the channeled whelk Busycotypus canaliculatus that has become established in San Francisco Bay in California since the 1930s, the family has never been found elsewhere. These are remarkably large snails: smaller examples are still more than five centimetres in length, and the largest of all get close to a foot (Petuch et al. 2015). Mature shells have a large body whorl, generally higher than the visible spire, with a long siphonal canal. SCulpture of the shell, if present, is dominated by spiral elements, and the shoulder of the whorls may be marked by prominent carinae and/or spines. As is standard for neogastropods, the classification of this group has shifted around a bit over the years, whether treated as their own family or as a subfamily Busyconinae of the related families Buccinidae or Melongenidae. In a recent review of the busyconids, Petuch et al. (2015) recognised fifteen living species in six genera. The number of fossil species that has been described is significantly larger (over one hundred); not surprisingly, these large solid shells have an excellent fossil record. However, it is worth noting that some of the living species may be remarkably variable in shell morphology and I don't know whether fossil representatives have been subject to the same systematic scrutiny.
Knobbed whelk Busycon carica, copyright Matt Tillett.
All busyconids are predators on bivalves, particularly on burrowing clams. In general, the whelk envelops its victim in its muscular foot and then uses the edge of the shell lip to open the clam's shell, allowing the whelk to insert its radula and rasp out the clam's flesh. The preferred method of opening the shell depends on the species of whelk and may be classed as 'wedging' and 'chipping'. 'Wedging' is the most straightforward method and believed to be the more primitive; wedgers insert the shell lip into the gap between valves and directly force them apart and/or prevent the clam shell from closing. 'Chipping' is more involved and performed by members of the genera Busycon and Sinistrofulgur. In this method, the edge of the whelk shell is rhythmically pounded against the commissure between the clam shell valves, progressively wearing at the valve margins until enough of an opening has been made to insert the radula. The process may take multiple hours of patient hammering. Chipping requires more power and a heavier shell than wedging (chipping whelks may damage their own shell as well as the prey's) but also allows the whelk to attack thicker-shelled clams.
Though each species of busyconid will generally use one or the other method of opening prey, there are borderline examples. Larger individuals of Busycotypus canaliculatus, usually a wedger, may adopt a process like chipping though their attacks on the prey shell are usually less systematic than true chippers. And while I haven't found anywhere that says as much, I suspect that young chippers may spend the earlier parts of their life as wedgers untill they have developed the shell strength for chipping. Dietl (2004) suggested that chipping behaviour may have originated twice among busyconids, based on the fossil evidence of its traces left on clam shells. The modern chippers appear to derive from a single origin in the later Pliocene. However, evidence of an earlier and now seemingly extinct chipping lineage was also found in shells from the late Miocene. These earlier chippers seemingly did not belong to any of the modern chipping genera which are not known from the Miocene deposits in which chipped clams were found. Instead, Dietl proposed that the culprit was a large Busycotypus.

Busyconid whelks have long been of significance to people living in areas where they are found. Not only are the shells eye-catching and ornamental objects in themselves, the animals are also harvested for food (though their meat is often sold under misleading names such as 'conch' or 'clam strips'). Archaeological examples have been found of busycon shells being used for tools; Petuch et al. (2015) illustrate an example of a left-handed whelk Sinistrofulgur sinistrum shell with holes drilled into it that would have allowed it to be attached to a stick and used as a shovel. These animals are truly an icon of North America's eastern seaboard.

A friend of mine is trying to identify this bug. It’s a few mm long, and it’s in her apartment in upstate NY. When crushed, she says it’s insides look “fuzzy.” Apologies for the blurry pic!
