* phylogenetic sequence #188900
Wingspan about 22-24 mm
Larva mature to 29 mm (Comstock & Dammers, 1935).
Pupa 12.5 mm (Comstock & Dammers, 1935).
New Brunswick to Florida, west to California, north to Manitoba. Range information complicated as species forms a complex with D. excurvata and D. setonana, adults of which are best separated by dissection.(1)
Adults fly from March to August, later in the far south. Larvae present from June to November.
Larvae feed on white-cedar and red-cedar. Comstock & Dammers found them abundant on ornamental Guadalupe cypress (Hesperocyparis guadalupensis) in suburban California and speculated they feed on wild junipers, as well.
Life Cycle
Two generations per year; overwinters as a pupa in soil or debris.
Larva; adult
This species forms a complex with D. excurvata and D. setonana and adults are best identified by dissection.(1)
