I essentially have the same question as my last post. I am curious about whether this Chironomid is from the subfamily orthocladiinae? This individual was collected in Mammoth Lakes, CA in June. It is about 2.5 mm. I am also wondering if anyone knows of any online guide for identifying subfamily and genus of chironomid.

I am not sure. Check the length of the fore basitarsus relative to the fore tibia. If the basitarsus is longer, subfamily Chironominae. If the ratio is less than .9, another subfamily and most likely Orthocladiinae. |

This reminds me of Corynoneura (Orthocladiinae). Have you any shots against a pale background?

@Tony No, I haven't, but part of me is starting to wonder whether it might be Simulidae rather than Chironomid becuase of the lack of cross veins. And input on this? |

The antennae and long legs rule out Simuliidae. |
