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.

The first one is either Limoniidae or Tipulidae. This depends on how many lobes it has : 5 in Limoniidae and 6 in Tipulidae. However, It looks close to Tipula sp. The second is definitely a Sciomyidae and it looks very similar to genus Elgiva sp. I have seen in Europe.

Thank you so much! I take it then that there isn't enough to say which family the first one is? Unfortunately this is the best look at the posterior I was able to get; you can see the bundles of setae all the way around but only four lobes seem plain to me, unless the little projection on the top left is one.

I have cropped, rotated 180 and tried to enhance the anal lobes and I think it is Limoniidae. There are 2 lateral and 2 ventral lobes and I think I can see only 1, unpigmented, dorsal lobe and not 2, pigmented, as in Tipulidae.
