Keuka Lake 20210807   2 comments

Two weeks at Keuka Lake in upstate New York! Pretty much all the photos were taken on the property of the house we stayed in, itself. Some woods, some leafy plants, some flowers.

Hemiptera

Beautiful Reduviidae nymph, probably Zelus luridus, and prey.

Woolly aphid, Eriosomatinae, perhaps Eriosoma?

Acanthocephala:

Reduviidae, Phymata pennsylvanicus. And the beetle is Typocerus velutinus.

This has to be the world’s laziest ambush bug, and the world’s most oblivious beetle. They stood there in this proximity for at least ten minutes.

Coleoptera

Is it in Carabidae? I don’t see a match.

Is it a Curculionid? The size of the spots on the pronotum don’t seem to match. The antenna is unusual for Curculionidae, but seems to match that best. Cryptorhynchinae? Entiminae?

Maybe something like Otiorhynchus sulcatus? That actually looks perfect, I’m happy with that ID.

Sumitrosis inaequalis

Chrysomelidae, Galerucinae, Trirhabda. Not sure what species.

Cleridae, Enoclerus nigripes.

Diptera

Syrphidae, Toxomerus geminatus.

Calliphoridae? Wing venation details would be useful, note the straight-ish vein. Maybe Lucilia sp.? I really know so little about Diptera.

I think “Acalyptratae” » Lauxanioidea » Lauxaniidae » Homoneura. But I can’t rule out Rhagoletis basiola in Tephritidae.

Trichopoda, feather legged flies,

Calyptratae » Oestroidea » Parasitic Flies (Tachinidae) » Phasiinae » Gymnosomatini » Feather-legged Flies (Trichopoda) » Subgenus Galactomyia (Trichopoda Subgenus Galactomyia) » Trichopoda pennipes

Dolichopodidae. Condylostylus is the most usual genus to classify them into.

I’m hesitant to even guess Anthyomyiidae, because it’s such a long shot and a I’m not really basing it on anything concrete.

Love these Condylostylus, assuming that’s the correct Dolichopodidae.

Not a clue.

Dolichopodidae.

Hymenoptera

Ichneumonidae? There are some Pimplinae that look a bit like this.

Encyrtidae, but maybe Eupelmidae instead?

Polistes fuscatus, in Vespidae.

Trypoxylon. Distinguished from Pemphredoninae by the little notch protruding into the eye at the middle level.

Vespidae. Polistes dominula.

Pompilidae? Priocnemis? Auplopos? Both Priocnemis and Auplopus have been suggested by people who know more than I do.

Further Pimplinae?

Halictidae. Augochlora pura?

Halictidae. Looks like Halictus.

Carpenter bee, Ceratina? I would guess subgenus Zadontomerus.

Augochlora pura.

Perhaps Apoidea –> Crabronidae, such as Crabronina –> Ectemnius or Crabro? Alternatively, Crabronidae –> Philanthus (beewolf)? I think Ectemnius or Crabro or something similar are the best match.

Distinguishing Crabro from similar genera (Crossecerus, Ectemnius, and Lestica)(3):
Recurrent vein ending before distal third of submarginal cell
Ocelli forming a low triangle
Lacking orbital foveae (sharp groove along inner eye margin)
Males front tibiae distinctly expanded

Upper frons evenly punctate

Identified as Cerceris in Solitary Wasps Forum, Facebook

Cerceris in Crabronidae.

Spiders

Platycryptus undatus, tan jumping spider, Salticidae.

Theridiidae spider, what’s the prey? A robber fly, I believe.

Pisaurina mira

Thomisidae, crab spider. I think Misumenoides formosipes (Whitebanded Crab Spider)

No Exoskeletons
