Numbers
2 species in North America listed at All-Leps
Size
wingspan of M. lappella 12-19 mm (1)
Range
throughout United States and southern Canada
also represented by several species in Eurasia
Habitat
fields, roadsides, waste places
Season
adults fly in June and July in the north; April to August in the south
larvae in late summer, fall, and spring (overwinter)
Food
larvae of M. lappella feed on developing seeds of burdock (Arctium spp.)
larvae of M. paucipunctella feed on developing seeds of knapweed (Centaurea spp.)
Life Cycle
one generation per year; overwinters as a larva in seedhead of hostplant; pupates in spring inside seedhead
