greenworms

Greenworms are the larval stage of the black carpenter ant (*Camponotus pennsylvanicus*), a common species found throughout North America. These ants are known for their distinctive appearance and behavior, particularly during their emergence from their nests in late spring or early summer. The term "greenworm" originates from the pale greenish hue of their exoskeleton, which is a result of their high fat content and the way they reflect light.

Greenworms are typically found in large numbers near ant hills, especially after heavy rains or during warm, humid periods. They are not true worms but rather the larvae of ants, which resemble segmented, elongated grubs. Their size can vary, generally ranging from 1 to 2 centimeters in length, with a soft, segmented body that lacks legs. Unlike adult ants, greenworms are immobile and cannot sting or bite.

These larvae play a crucial role in the ant colony’s life cycle, serving as a food source for the queen and worker ants. When disturbed, they may release a foul-smelling fluid as a defense mechanism. While greenworms are harmless to humans, their presence in large numbers can be unsightly and may attract other pests, such as birds or rodents, which feed on them.

Greenworms are often mistaken for other larvae, such as those of beetles or flies, but their association with ant hills and their seasonal emergence help distinguish them. They do not survive long outside the nest and typically die within a few days if not consumed by predators or returned to the colony. Proper nest management, such as reducing moisture and eliminating food sources, can help minimize their appearance in residential areas.
