Taxonomy

Family: DERBIDAE
Taxonomic Author: (Ball, 1902)

Identification

Online Photographs: BugGuide, GBIF iNaturalist Google
Description: Adults are bluish overall (dark bluish-black wings with lighter blue waxy coating, characteristic of the blue Cedusas) with dark, orangeish legs. The male phallus (reproductive claspers) has two large, broad 'plates' that almost resemble clam shells, distinctive from many of the other blue Cedusas (see image above).

Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec

Habitats and Life History

Habitats: Has been found in grassy, brushy habitat near forest edge.

Plant Associates: Derbidae are known or assumed to feed on fungal hyphae as immatures (UDEL).

Behavior: Probably can be attracted at night with a light.

Comment: A majority of Cedusa look very similar externally, appearing bluish overall. The only way to make a positive ID for many of the species at this point is to examine the genitalia of the males. Therefore, a male specimen is necessary for many species' identifications. Detailed, clear photographs of the male underside showing the genitalia can also be helpful, and perhaps the hope is that after observing enough specimens of a particular species, there may be slight external features that can be associated with an ID.

Status: Native

	Photo by: Ken Kneidel Mecklenburg Co. Comment: This female was caught in the same sweep with a Cedusa obscura male, so it's likely this is also C. obscura. Habitat was an open, weedy, marsh.
