Numbers
5 species in 1 genus in our region
Food
Lecanodiaspidids are normally collected on the stems or branches of woody shrubs or trees and are not recorded from grasses and most herbaceous plants. The family occurs on a diverse array of host plants encompassing about 67 different plant families. The most common hosts are in the family Fabaceae, Fagaceae, Myrtaceae, Moraceae, and Rutaceae. Nearly twice as many species occur on fabaceous hosts as on any other host family. (from Scale Insect ID Tools: Lecanodiaspididae)
Life Cycle
False pit scales apparently have 3 instars in the female and 5 in the male. Lecanodiaspis prosopidis (Maskell) has 1 generation each year and overwinters in the egg stage inside the adult female test. Eggs hatch in early spring, and first instars leave the test through a small hole at the posterior end. Second instars appear in early to mid summer. Adults are present in mid to late summer, and eggs are laid in the fall. Males probably occur in most species. Species in other genera are frequently tended by ants and are found in carton tents or hollow stems. (from Scale Insect ID Tools: Lecanodiaspididae)
Remarks
Lecanodiaspis only genus found in the U.S.
