Adult males emerge as tiny two-winged insects.
The female s body is underneath the armor. Nymphs resemble adult scale insects but are smaller and female nymphs lack the spot. Intermediate adult females overwinter and produce a clutch of eggs underneath their scales in the spring. Adult females develop from the second nymphal stage in about 12 days, and winged males develop through this stage for about 5 days before emerging as winged adults 7 or 8 days later. Development from egg to adult can occur within 35 to 40 days.
