Dear all
A few larvae of this strange looking Eriopterinae were found by a co-worker in a spring near Ulestraten in the southern part of the province of Limburg in The Netherlands on 6.iv.2011 (50.53'57" N, 5.46'21" E). To me it looks like some species of Ellipteroides or Gonomyia, but the literature on these larval species seems non-consistant, i.e. there are some differences. in Ellipteroides the anal lobes are distinct while in Gonomyia the lobes apparently are less protruding. So this appears as an Ellipteroides sp. and E. alboscutellata seems the more likely species. However, the lobes, especially the lateral, as drawn in Savchenko (1982) are not as protruding as in my specimens unlike the drawing in Bangerter (1920) were the lateral lobes are about the same as mine.
In our larvae there are no ventral pseudopods, the dorsal anal lobe is distinctly shorter and slightly pigmented, the lateral lobes are fully pigmented and the ventral lobes are divided.
Any idea?
