I’m pretty sure this is a daring (or bold) jumping spider, Phidippus audax. He was very, very large, though you can’t tell it from the photograph. Found at same location as the spider I posted earlier. It was a good spider day (and there’s even one more). Swarthmore, PA.
Pretty sure this is Hibana gracilis, a garden ghost spider. Some ghost spiders eat insect eggs, others slice open leaves to extract leaf miners. I’m not sure what this one does other than it does it during the day, unlike most in the family (Anyphaenidae).
Copulating pair of Taeniaptera trivittata, a type of still-legged fly (Micropezidae). Males (or females, according to one source) apparently brush the eyes of the partner during mating, though this frame didn’t capture that. When flitting around leaves they wave their white-tipped forelegs and look just like small ichneumon wasps. They have thin waists but the pattern on their wings makes them look even thinner, waspier. Known to feed on rotting Typha, which was abundant nearby (John Heinz National Wildlife Refuge, Tinicum, PA).
If you come across a pair, please take a video so I can see the legs in action. I like to watch, and I know of others who are interested in this species.
Some photographs of me donating blood. The first is, I think, an Asian rock pool mosquito (Ochlerotatus japonicus japonicus; formerly known as Aedes japonicus japonicus). The second is an Asian tiger mosquito (Aedes albopictus). Introduced to New Jersey in 1998 and Texas in 1985, respectively. Both photographs were taken in Pennsylvania.
Found a bunch of these flat-faced longhorn beetles on a dying tree a few weeks ago. I’m fairly confident it’s Astylopsis macula. But there are a gazillion genera of Lamiinae, so I’m happy to be corrected. Would also be very happy to hear from anyone who knows what elytral pits do, other than providing handy identification. I’ve wondered about that for years. Are they vestigial patterns from forewing ancestry? Sound-dampening trick to elude echolocating bats? Are pits just decorations, useful in crypsis or for intraspecific recognition? If you know, would love to hear from you.
