Homerus Swallowtail
The largest butterfly in the Americas, with a wingspan reaching 150 mm and bold black and yellow patterning. It is endemic to Jamaica and restricted to two mountain ranges.
Did You Know?
Fewer than an estimated 500 adults exist in the wild, confined to shrinking patches of Jamaican mountain forest.
Slender Pigeon Louse
A long slender louse found between the barbs of wing and tail feathers of pigeons and doves. It is one of the most studied louse-host systems in biology.
Did You Know?
This louse has become a model organism for studying coevolution, as its evolutionary tree closely mirrors that of its pigeon host species.
