Synonyms and other taxonomic changes
consors LeConte
vestitus LeConte

Hatch(1) notes that "LeConte and Arnett [were] in error in considering vestitus LeC. a variety of gracilis LeC. rather than of this species. This potential error seems to be carried over in recent literature. The "vestitus" form refers to specimens from the west that possess golden pubescence (swBC to nwOR).
Explanation of Names
Ditylus quadricollis LeConte 1851
Size
12-23 mm(1)
Range
AK-OR to AB-ID(1)(2)
Habitat
Found under cover around logs in forested areas, also on flowers; reported breeding in logs of Thuja plicata, Pseudotsuga taxifolia, and Picea engelmani (Guppy, Leech, Arnett)(1)
