Common Blue Butterfly (larva/caterpillar stage)

Grassy meadows, gardens, and heathlands across Europe, North Africa, and temperate Asia.

Larvae primarily feed on Bird's-foot Trefoil and other plants in the pea family (Fabaceae). Adults feed on flower nectar.

The larvae have a mutualistic relationship with ants; they produce a sugary secretion that ants feed on, and in return, the ants protect the larvae from predators.

Provides ecosystem benefits as a pollinator in the adult stage and serves as a food source for birds and spiders.
