During courtship the male hovers about an inch above the female and 3/4” behind her. I wonder what he targets for his stationkeeping. It might be the shiny overlapping wings, or perhaps the blue spots. Sounds like a field experiment is in order...

Thanks Troels!

The back of the head UV shot is not much of an image. A bit too fuzzy for my taste.

But the result is interesting.

And here is an image of the back of the head in UV. The blue patches don’t lite up more than other areas. I don’t know if this is because the orientation allowed UV to reflect away, but I suspect not. I think the patches are blue as the eyes of the bug may be tuned to blue wavelengths for max sensit...

Stereo of the back of doli's head

A ~ 10X photo of the back of a dolichopod's head. This fly inhabits the muddy bank of a stream. The male hovers over the female about 2cm back looking over her folded wings and toward the back of her head. I puzzled over these spots till I observed the courtship and now suspect that the spots are wh...

One more thought on animal vision books. Visual Ecology is excellent. A bit pricy though.

Oh yes, I see the tear . So the shell looking bits in the fuzzy covering. Most interesting.

Where there no hollow shell I would think of the spider egg masses I occasionally find in my basement bug photography studio. Most interesting!

The asymmetry in appearance of the large central eyes is quite interesting. It appears the rental cells of the eye on the left may be visible? A seldom imaged phenomena.

Very nice!

Are the holes in a star pattern for venting? Is there a fan mounted beneath? Or a speaker?

Yawns,

What I like about this is that there is no way to accidentally gas yourself with the minute amount of CO2 made in your chamber. I look forward to trying this technique later this year.
