Some more neat bugs.

Although fall migration is going on I'm not seeing much. So here's some more bug pics. A few days ago I found my first Evening Skimmer on the Green Jay trail at Estero Llano Grande State Park. It's a crepuscular species that spends the day in a dark wooded area. I later found a couple more of them outside the headquarters at Santa Ana NWR. This is one of the rare RGV odes.

Another new one for me was the also crepuscular Bar-sided Darner, another RGV specialty. This one was at Estero Llano Grande.

After finding the darner, a special treat was this superb Two-barred Flasher.

New Damselfly for the USA.

A couple of weeks ago Terry Fuller from San Benito found a colony of Telebasis damselflies near his home that he was pretty sure was not the usual Desert Firetail. He did some heavy duty scientific sleuthing and discovered they are a new species for the United States, Telebasis digiticollis. Here's a link to his pics. He later found a large colony nearby that is easy to access. The previous northernmost site for this species was in the Mexican State of Veracruz. Here's a pic of the new bug.

The specific epithet (species name) "digiticollis" refers to two horns of the prothorax of the female. Here's a female but you can't see her horns.
