Lacewing Fly

Family Nymphomyiidae

The family Nymphomyiidae represents a small, extremely rare, and ancient lineage of true flies. It is crucial to distinguish these obscure insects from the common and beneficial 'Lacewings' (Order Neuroptera), which are well-known garden predators. True Lacewing Flies are not found in Australia. They are of purely scientific interest and are not pests. They have a unique life cycle, with aquatic larvae living in cold, fast-flowing streams. The adults are non-feeding and short-lived. This entry serves to clarify their identity and differentiate them from the familiar beneficial insects that share their common name.
