Micromus tasmaniae, known as the Tasmanian brown lacewing, is a species of brown lacewing in the family Hemerobiidae. It is widespread in Australia, New Zealand, and Pacific Islands such as New Caledonia and Vanuatu. Adults of the species are 7.5–10 mm (0.30–0.39 in) long, and are typically nocturnal. The lacewing's lifespan is temperature dependent (higher temperatures causing shorter larval stages). The Tasmanian Brown Lacewing breeds all year round, surviving at temperatures as low as 5 °C (41 °F). The species typically has clear wings and a brown body. The species can be differentiated from Micromus bifasciatus by the spotted pattern on the species' anterior wings, compared to the brown transverse bands found on Micromus bifasciatus.
The lacewings feed on nectar, as well as aphids and psyllids. The species is found widely across Australia, and is likely the most common species found in both Australia and New Zealand. The species has been established in New Zealand since at least 1869, and has been identified in remote areas of the country, including the Chatham Islands, Auckland Islands, Antipodes Islands and Kermadec...

GBIF citizen-science records
It is estimated from how often the Tasmanian Brown Lacewing is recorded against all the insects logged in Great Otway National Park (18 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
