Cethosia cydippe, the eastern red lacewing, is a species of butterfly from Australia, New Guinea and nearby islands. The Australian subspecies, C. c. chrysippe, is known as the red lacewing butterfly. The imagines have scarlet wings with thick black edges and a diagonal white patch on the forewings. The underside is orange with similar white patches and lines of black spots, each with a white outline. The wingspan is around 8 centimetres (3.1 in).
Pale yellow eggs are laid in groups of 50 on the host plant. The caterpillars which hatch from those eggs are herbivorous, feeding on vines in the family Passifloraceae, including Adenia heterophylla (lacewing vine) and Passiflora aurantioides (Queensland passion-fruit). They are black with yellow bands and long black hairs, and form congregations on the host plants. The pupae are brown and spiky with black and gold markings, hang from a cremaster and resemble a dead leaf.
It was described by Carl Linnaeus in the 1767 12th edition of Systema Naturae as Papilio cydippe. He had previously described a European species, now classified as Argynnis, under that name in... Wikipedia →

With luck
About 10% of wildlife watchers report an Eastern Red Lacewing Butterfly sighting in Daintree National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 567th most-seen of the 856 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January and May–August
In those months about 10% of wildlife watchers report an Eastern Red Lacewing Butterfly in Daintree National Park on a given day, against under 5% in February–April and September–December, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eastern Red Lacewing Butterfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Daintree National Park, in our data
Daintree National Park is the only park on Wallace's Line with enough records to rate Eastern Red Lacewing Butterfly sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Eastern Red Lacewing Butterfly is recorded against all the insects logged in Daintree National Park (8 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.
