Hello all. I was going through some old microscope photos and there were two fly larvae I thought I could use some help with. Both are from Alberta, Canada. The first is about 3½ mm long from a shallow marshy spot. I am guessing it is a limoniid but I am not familiar enough with them to be sure I haven't misinterpreted the lobes at the posterior.

The second one is about the same size, from near a stand of cattails in a stormwater pond. This one doesn't seem to have a head capsule and my best guess is it might be a sciomyzid, but I couldn't find any that looked similar enough to have much confidence in that.
