Your photography just blows me away!
I wish I could take a few lessons over there. Are you photographing through a dissecting microscope??

Thank you for your kind comments!
These photos were taken using a dissecting microscope and focus stacking approximately 47 images with the Helicon software. In the last six months, I usually photograph dead insects under 3 mm this way. Insects that are 3 mm or larger, and all live insects, are mostly imaged with the equipment described in my profile. There was a steep learning curve for me when I first started photographing insects through the dissecting microscope and there are more than a couple of "tricks" manipulating the light, background, camera settings, and post-processing, but obtaining decent photos of small bugs is not difficult at all if you have the time and patience.

It is always a pleasure for me
to provide serendipitous finds to BG. The guide is the epitome of synergy and collaboration.

Comment by Dr. Heydon…
"Nice photos. This creature is
Eutrichosoma mirabile
. This is a fairly common species, but the host is still unknown. It has been suggested that it might be a weevil. If the contributor could find the host, that would be great".
Well done - a wonderful find for BG. A new subfamily, genus, and species can be created for this pteromalid. There are only two NA species in this particular genus -
Eutrichosoma mirabile
and
E. flabellatum
.
The new subfamily is
Eutrichosomatinae
, and the new genus is
Eutrichosoma
. [
Eutrichosoma mirabile
Ashmead, 1904]

My pleasure…
The new subfamily reference should still be included at some point - hopefully one of our editors will get to this soon.

Chalcid…
Possibly a pteromalid - will ask Dr. Heydon.
