All your photos are Chironomidae.
Chaoborus has more wing veins.
Females of the common species of Chironomidae have fewer segments in the flagellum (5-6 compared to more than 10). The last two photos are exceptions to the second rule --Ablabesmyia and Procladius in subfamily Tanypodinae.
Males can also be distinguished by antennae and genitalia. Males have distinct rings of hairs and longer genitalia with a slender dististyle.
Hi John,
Thanks for identifying my pictures as Chironomidae. These guys (picture attached) emerged from my traps this past week. I assume these are male and female Chaoborus (any way to tell if they are Chaoborus flavicans?). Based on the antennae with distinct rings and the wing veins, they do seem very different from the Chironomidae (even without a dissecting microscope)!
