Here is another one of those tiny flies I've been trying to ID. They are active hunters of springtails and barklice. They are also very, very common in my yard.
They seem rather reluctant to fly, but would rather run. They also seem to be on vertical surfaces more often than not.

Moved from Longlegged Flies.

This callow (freshly emerged) male specimen belongs to the genus Medetera (Dolichopodidae, subfamily Medeterinae). The majority of Medetera species is indeed found on vertical surfaces such as tree trunks and larvae of many species seem to feed on bark beetle stages (Coleoptera: Curculionidae, Scolytinae).

Cool, Thank you!
These guys are all over the place in my yard. The adults seem to like barklice & springtails, I haven't seen any larvae.
