Tabanidae?? - Chrysops carbonarius - Female
Port Sanilac, 47°27.2' N 62°33.3' W, Sanilac County, Michigan, USA
November 18, 2009
Is the coloration of the wings something typical for Tabanidae or rather not?
Can anybody show me a good picture of calypteres, I have difficulty to picture them or see them on my specimen if it is Tabanidae...

Thnx

yup, a Chrysops
must be IDable
never heard of tabanids with calypters -- they are an attribute of a very diff. dipteran lineage

In Borror and DeLong's Introd
In Borror and DeLong's Introduction to the Study of Insects by Triplehorn and Johnson it says.

Order Diptera -> Key to Families

Step 36
Calypteres large and conspicuous

Step 37 (Tabanidae)
Both upper and lower calypteres large

Thats why I was asking.

really... wow -- you're right
they just look so different -- i'm lucky to never have had to use keys above genus level over the last 30 years :-]

here you can see clearly both calypters, the upper [in plain sight] and the lower [just in front of the halters]

Thanks so much. Dipterans are
Thanks so much. Dipterans are not my strong suite.

The calypteres were kinda hidden underneath the alula the way the wings are on my specimen.
