Hypolimnas alimena, the blue-banded eggfly, is a species of butterfly in the family Nymphalidae. It is found in the Solomon Islands, Indonesia (Aru Islands, Irian Jaya, Kei Islands, Maluku,Timor), New Guinea and Australia (the coast of New South Wales, the Northern Territory and Queensland).
The wingspan of H. alimena is 80–90 mm. The ground colour of the wings is black with a row of white dots and a blue band. These butterflies resemble closely to related species,H. bolina.The males exhibit less visually elaborate structural coloration, as compared. The dorsal blue coloration of this butterfly has weak iridescence, and is not very bright. This is because it arises from a simpler nanoscale surface structure, unlike the more complex nanoscale multilayer-arrays structure of H. bolina, which gives it a brighter sheen and saturation.
The males of this species primarily utilize a sit-and wait-strategy for locating mates. This behavior is similar to Hypolimnas bolina. However, unlike H. bolina, these males do not engage in extended aerial disputes for the territorial defence. Both of their flight morphology is strikingly similar, and does not show any significant... Wikipedia →

Possible
About 20% of wildlife watchers report a Blue-Banded Eggfly sighting in Daintree National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 90th most-seen of the 856 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–May, July, October and December
In those months about 20% of wildlife watchers report a Blue-Banded Eggfly in Daintree National Park on a given day, against under 5% in January, the lowest month.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Blue-Banded Eggfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Blue-Banded Eggfly sightings, Daintree National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Kakadu National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Blue-Banded Eggfly is recorded against all the insects logged in Daintree National Park (30 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.
