Upon death, Myrmex drop Myrmex Chitin (corresponding to the Myrmex variant), Myrmex Resin Chunks (also corresponding to the Myrmex variant), and Myrmex Stingers. Myrmex can be located in Myrmex Hives, vast, labyrinthine, underground nests that are made of resin and bioluminescence, and can be found in Desert and Jungle biomes. Myrmex pupae are also white in color, although their body plan resembles their adult forms far more than the larvae. Myrmex larvae are white in color, and lack limbs and mandibles, making them resemble small worms.

Myrmex come in 2 colors, depending on where they are found desert Myrmex are brown in color, while jungle Myrmex are cyan in color. The Queen is the largest of the Myrmex castes, and bears a resemblance to the Worker, but with a pair of horns on top of her head, and with a long, pulsating, sac-like abdomen.Royals resemble the Workers, but are much larger in size, have a slightly lighter body pattern, and boast 2 pairs of wings that they can fly around with.Sentinels differ the most from the standard Myrmex body plan their first pair of walking legs have been modified into raptorial forelegs, their abdomen has been modified into a long, curved, scorpion-like tail, and they stand upright, much like a praying mantis.Soldiers resemble the Workers, but are slightly larger in size, have a slightly darker body pattern, and have larger mandibles.Workers have the standard Myrmex body plan, with 3 pairs of walking legs, a body held parallel to the ground, and a bulbous abdomen.As eusocial arthropods, the Myrmex are quite diverse in body plan, and come in 5 different castes, with most castes having many unique features: Although Myrmex differ in body plan depending on what caste they are, they all resemble giant insects (more specifically, ants) with hard, chitinous armor, 3 pairs of walking legs, a moderate-sized thorax, a moderate-sized head with large, yellow eyes and large mandibles, and a large, bulbous abdomen ending in a sharp stinger.
