. We have not found any consistent, morphological differences between specimens in the small and large end of the size range. There is some variation in the apparent pigmentation of the wings, but this is probably of taphonomical origin as the venation seems very similar. Among the> 1000 bibionid specimens from Enspel in GDKE seen by the first author, this species probably makes up about 90%.
