(Guérin-Méneville, 1845)[1]

This species is the largest and most notable species of ant of Cuba. A. insularis is unique to Cuba, and has great polymorphism. Its workers specialize in different activities. The warriors have remarkably large heads.

They prefer to work at night, although they do by day, more if on cloudy days.

The nests are huge, and may comprise one or several mounds that can be spaced several metres apart. The height of the mound can sometimes exceed a metre. These nests in natural sites can be very durable, even more than 50 years.

This species is a pest of citrus, coffee,[2] and various Pinus species.[3]

Quantitative studies in the behaviour of A. insularis has been performed both in laboratory-controlled conditions,[4] and in the wild.[5][6]

gollark: `pos =` only assigns to the `pos` local variable inside the `checkerpos` function, which I assume is your issue.
gollark: It's generally cleaner to just *return* the new version of something.
gollark: I would generally recommend against global variable use.

gollark: If you obtain money by making some sort of innovative product/service, you're improving things for everyone who wants the product.
