Phidippus audax visits the house   2 comments

Trying to capture the beautiful color of the chelicerae, but it didn’t come out right in the photos.

First bug walk of the season (as opposed to the vernal pool and the wetlands). I spent a lot of time (too much time) creating many, many candidate flash diffusers. Today was the first actual trial.

Plenty of insects and spiders!

Diptera:

My guess: Hexomyza schineri in Agromyzidae. However, I’m told that it could plausibly be many others that are acalypterate.

Lonchaeidae

Bibionid

Who is this? I was about to call it Bibio longipes — and then discovered that that is found only in fall. Maybe something like Bibio femoratus?

Anthomyidae, cf Anthomyia.

Another Bibio cf femorata?

Such a striking fly, probably Agromyzidae.

Male Bibionidae?

Hymenoptera:

A mutillid wasp. Pseudomethoca simillima?

Cynipid wasp

Nomada luteoloides?

Probably Andrena.

Coleoptera:

The requisite six spotted green tiger beetle:

Notiophilus cf biguttatus

False blister beetle, Asclera ruficollis, in Oedemeridae? Or Podabrus punctatus? I *think* it’s Asclera ruficollis. But Pedilus lugubris is another possibility. Okay, now I’m going with Pedilus lugubris.

EDIT: according to BugGuide, Silinae in Cantharidae is the best starting point.

“Anthonomus, I believe, either A. suturalis or A. musculus.”

Elateridae. Maybe Dolerosomus silaceus?

Tarpela micans. For some reason, I only seem to see dead ones.

Spiders:

This beautiful Lycosid. Pardosa sp.

Naphrys pulex. Except that it might be a Pseudeuophrys erratica, which I’m just learning about — introduced from Europe. Or Habronatus?

Thanatus, in Philodromidae.

Solsticus insularis? Haplodrassus cf hiemalis? Callilepis pluto? Urozelotes isn’t confirmed in BugGuide near here, but I’ve seen it suggested (https://bugguide.net/node/view/1791543) for Massachusetts, so maybe this is that?

EDIT: Zelotinae looks good, but classifying any finer is highly questionable.

Opiliones (aka Harvestman):
