Judging from the corrosion on the surface, this was not from last year’s grapes. Perhaps the vintage was worthy of straight consumption and not dilution with orange juice? ????

This is a very interesting topic and the images are excellent. I have pondered this and have this to offer. The SEM images Rik linked are quite interesting. They show a lot of the structure, but the sputtered metal to allow the SEM may be a bit thick. The images Rik found were more of a survey of SE...

Interesting. I will do some sweep netting above the lawn this afternoon and look more closely. Cooler weather and rain arrive this evening.

doli stereos

My 2019 bug season is drawing to a close in Northern Illinois. It started in April when I found a doli (long legged fly) by the nearby creek when I watched for warblers. It ends at the same spot with a different doli. Cold temperatures in our future. All photos with my 10X Oly objective, 200mm Penta...

Thanks for posting!

I presume the coloration is camouflage?

This is quite ornate. Much more so than the small moths that fly up from my lawn in late summer when I mow. Often a flycatcher perches in the trees and swoops down and picks them off. An adaptation to suburbia.

The male in image 5 appears to be the lesser of two weevils.

Sorry, couldn’t resist.

Dolichopodidae (long legged flies) are quick, but in a manual flash mode I can usually catch them. In an auto mode they are often spooked.

This is a female Condylostylus caudatus type. And your image is excellent.

surface structures (textures) nomenclature

In the course of correspondence with an entomologist pal, I discovered that there is an official nomenclature for describing the various surface textures on insects. Who knew? https://zenodo.org/record/26215#.XY0F0oxOmhA If this link fails then try Googling “ a glossary of surface sculpting, Harris ...

Doli in ermine coat

I discovered a long neglected fly carcass in a collection cup. It looked like it was taking a bubble bath or wearing a white fur coat. I had placed the fly in a cup with a moist sponge to help keep it alive long enough to lay eggs. After it expired I collected the eggs and made a time lapse movie of...

Rik wrote There was an impressive amount of damage! Yes, but compared to the feeding habits of Preying Mantis that grind up and consume nearly everything but the wings, spiders are quite dainty in their treatment of flies.
