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.

thanks all for the nice addition!
Moved from Chalcid Wasps.

 
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]

Outstanding!
Thank you Ross for following up this entry to a happy conclusion.

 
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.

Thank you Ross!
