Conifer Seed Bugs (Leaffooted Bugs) - Leptoglossus
occidentalis   Sandy Kegley,
USDA Forest Service, www.ipmimages.org
 HOSTS: Primarily pines, douglas-fir, and dogwood; occasionally other
plants. DESCRIPTION:
They are
reddish brown to a dark gray color with light markings on their
abdominal margins. The hind tibia is broad and flat (hence the name
leaffooted bug). They range in size from 5/8 to 3/4 inch long. LIFE
CYCLE: Adults
overwinter in a sheltered site (frequently in nearby homes). In spring
they move to trees and feed on the male flowers and year-old cones. In
late spring, the females lay eggs in small groups glued to needles and
leaves. The immature stages (nymphs) feed on seeds throughout the
summer and mature in late summer. As adults they continue to feed on
seeds until moving to a protected shelter in the fall. CONTROLS:
None
necessary. |
