Simuliidae - Black Flies.
A selection of images.

This page is still under construction. The images presented here are a small selection of a large collection made by various people over the years, from the now defunct Department of Entomology, University of Alberta. Eventually there will be explanatory text with each image and they will form part of a project to put Medical Entomological images on the WWW. For the present, just enjoy them. The size of file that is indicated in brakets following each label is the compressed size.
Another series of similar images, but with a more hydrodynamical bent can be reached from here
