Cedar Creek
Ecosystem Science Reserve


The most extensive collecting of CCESR insects has been conducted in its abandoned fields and experimental grasslands. More than 30 fields have been routinely swept for insects four or more times per year since 1987. Insects have also been collected in several of the major Cedar Creek experiments, where plant productivity and diversity have been experimentally manipulated. A limited amount of pitfall trapping has been conducted in old fields, savanna, marsh and woods. Some D-vac sampling of insects in experimental grassland plots has also been conducted. Insects collected in non-field habitats has been more or less a haphazard affair. I seldom go anywhere without my net or pooter and collect any interesting critters encountered. Light trapping has been limited, but an LTER intern, Sue Seabolt, did a fine job of light trapping for moths near the lab. Other modes of collecting (malaise traps, Berlese funnel extraction, removing bark, etc.) have received minimal effort. Aquatics, with the exception of the Odonata, have also received minimal attention.

With the exception of a few groups, most identifications have been made by myself, and in many groups these identifications must be regarded as tentative. John Luhman kindly identified nearly all the Ichneumonids and Braconids. Phil Clausen has examined the Ephydridae, Cerambycidae, and a miscellany of troublesome Coleoptera. John Lattin has examined all the Hemiptera excepting Miridae which were examined by Michael Schwartz. Robert Dana, Michael Sabourin, Susan Weller have looked at many of the Macro Lepidoptera. I hope this listing will prove a stimulus for other specialists to examine material in the collection, or better yet, come to Cedar Creek to collect groups that have been relatively ignored.
