Butterfly populations are a very good indicator of the health of an area's ecosystem !!
Longwings participate in a fascinating behavior known as communal roosting.
Circadian communal roosting in butterflies occurs when a number gather to rest for the night, typically on a single branch. These communal roosters can be quite numerous and can consist of single or a variety of species.
Each evening, the air around the roosting site fills with butterflies as they work to find an open spot on the roost. The whole process takes about an hour to complete because the new arrivals tend to agitate the butterflies that perched earlier.
Unless the roosting site is disturbed, the same butterflies will visit that spot night after night. Strength in numbers is one of the benefits of communal roosting for Longwings.
Avg. Wingspan: 72 - 100 mm / 3 - 4 "
Diet: adults feed on nectar and pollen.
(Longwings are only butterflies known to consume pollen, which is probably why they have a long lifespan.) (about six months, as compared to a more usual one month for other butterfly species).
