Papilio aegeus, the orchard swallowtail butterfly or large citrus butterfly is a species of butterfly from the family Papilionidae, that is found in eastern Australia and Papua New Guinea. The larvae of this species are sometimes considered a pest, due to their feeding on citrus leaves in suburban gardens.
Both male and female have black forewings with a white stripe, though there is more white overall on the female forewing. The hindwing is again black, and there is a white swath through the middle. Here the markings differ in that the female has chains of red to orange and blue crescents toward the edge. The markings on the underside are similar to those on top. The body is black. The wingspan is about 140 millimetres (5.5 in) in females and 120 millimetres (4.7 in) in males, making it rather large overall and the largest butterfly commonly seen in at least part of its range.
Despite being a swallowtail, which group derives its name from the distinctive tails on the hindwing, this characteristic is entirely absent. Karl Jordan in Seitz. describes the forma (pages 65–67) Papilio aegeus can be found in every state in... Wikipedia →

Possible
About 30% of wildlife watchers report an Orchard Swallowtail sighting in Lamington National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 430 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report an Orchard Swallowtail in Lamington National Park on a given day, against under 5% in May to August, the lowest months. That is one of Lamington National Park's wettest months, with about 160 mm of rain against 40 mm in August.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Orchard Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 parks where we can rate Orchard Swallowtail sightings, Lamington National Park has the highest daily chance: about 30%. Next come Springbrook National Park (Australia, about 20%) and Raja Ampat (Indonesia, about 20%).
Same family: Papilionidae
The closest relatives of the Orchard Swallowtail that you can see in Lamington National Park (family Papilionidae, Swallowtails and Parnassians) are Richmond Birdwing (about 30%), Macleay's Swallowtail (about 20%) and Four-Barred Swordtail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orchard Swallowtail is recorded against all the insects logged in Lamington National Park (80 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.
