Biston robustum

[1] This species has recently gained attention due to the discovery of its use of chemical mimicry to avoid predation by ants.

The larva of this species, in common with many other geometrids, uses visual mimicry, strongly resembling a twig of its host plant.

Recent studies have shown that it also uses chemical mimicry, storing chemicals from its food in its cuticle so that ants are largely unable to distinguish it from a twig, even after making contact with their highly sensitive antennae.

Ants foraging for prey have been observed walking along the moth larvae, oblivious of their presence.

The larvae of this species are polyphagous, feeding on a wide range of different plants including:
