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 →

With luck
About 10% of wildlife watchers report a Blue-Banded Eggfly sighting in Raja Ampat on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 46 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February–March, August–October and December
In those months about 20% of wildlife watchers report a Blue-Banded Eggfly in Raja Ampat on a given day, against under 5% in January, April–July and November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Blue-Banded Eggfly is recorded against all the insects logged in Raja Ampat (6 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.
