On Platanthera stricta
Tons of flies on the surface of the Great Salt Lake.
California Gull chases brine-flies, the abundant food source(along with brine shrimp) which draws so many migrating birds to the Great Salt Lake in fall.
Thousands upon thousands of these flies along the causeway to Antelope Island. Wonderful source of food for the many birds that come here.
Personally, I think teenager shoes smell awful, but the brine flies do not share my opinion! @redston_1
I imagine this is a Theridion but I'm going to do some reading to see if I can make a more educated guess.
About 4mm. Thick black mark at base of anterior abdomen and thin dark border line on carapace. I have a few more angles of this one if anyone wants to try and help me get a solid ID.
