Living With Blister Beetles

In the previous post, I mentioned that Blister Beetles have hypermetamorphosis. Why? Most larvae of insects with complete metamorphosis are well adapted to a single task: feeding. Typically, the adult female lays eggs near a food source.  Larvae must cover a short distance or even none at all.

Blister beetles do not lay eggs on food. Larvae must travel to find their food.  A mobile larval stage the triungulin (A), is required. The triungulin larva has long legs which can travel larger distances more efficiently. Once it has found a food source, the triunglin form is less well adapted to processing food, molting and rapid growth. The triungulin molts to a form with shorter legs and larger abdomen that facilitates more rapid growth.
