The lac insect is a highly gregarious insect. It normally forms what may be called a giant colony or stick lac and the minute morphological and physiological differences, difficult to observe separately are obvious in their totality by comparing specimens of stick lac belonging to two different species of lac insect. The species Lacshadia communis, even in the larval stage does not spread out its colony so intensively as Lacshadia chinensis. Lacshadia mysorensis is the only insect which has three life cycles a year, and the while its productivity has increased its size decreased, just as is the case with polyvoltine silk worms.
