Cleridae

Definition

Checkered beetles. Arrive at remains to feed on other insects, particularly fly larvae and small beetles. They are secondary predators and their presence indicates a significant primary fly colonisation has occurred or is underway.

Common questions

Why does finding Cleridae on remains matter for PMI estimation?+

Because they are predators rather than direct decomposers, their presence tells an entomologist that fly colonisation has already progressed far enough to support a prey population, which helps constrain the minimum time since colonisation began rather than dating decomposition directly.

How are Cleridae distinguished from the fly larvae they prey on at a scene?+

Cleridae are adult or larval beetles with hardened, often colourful mottled elytra or a distinct beetle larval body form, clearly different in shape and movement from the soft, legless fly maggots they are feeding on.
