Phasmatodea: A Practical Species Guide

Stick and leaf insects are famous for one thing: looking like the plants around them. That is the part everyone falls in love with. But after a few months of keeping them, the camouflage is not what shapes your routine. The biology underneath is.

Phasmids vary enormously across lineages. Some species are happy with low humidity and almost any leaf you put in front of them. Others are picky to the point that the wrong host plant will quietly kill them over weeks. Some drop eggs from a perch and forget about them; others actively place them in substrate and need a very different floor design as a result.

When I read a species description now, I skip past the visual notes and look for three things: how it molts, how it drinks, and what it actually eats in captivity versus in the wild. Those three answers tell me almost everything about how the enclosure should be built. Camouflage is the marketing. Functional biology is the husbandry.
