Adult Brown Lacewings

Lacewings have been used successfully for years in the greenhouse industry. We are pleased to introduce a commercially produced brown lacewing, Micromus variegatus.


The adults are typically 6 to 12 mm long and are mostly brown or blackish in colour with brown patchy wings. The larvae are elongate and small-headed. This lacewing is found naturally in wooded areas throughout North America. Both adult and larvae feed primary on aphids, mealybug, thrips, leafhoppers, and mites. 


Unlike most green lacewings, brown lacewings are predatory at all mobile stages ot their live-cycle. In fact, it is the adult that does most of the predation, usually at night.
