The #dockbug #Coreus #marginatus (#Coreidae, #Heteroptera) is distributed from Europe to Asia and parts of Africa. It feeds e.g. on docks and sorrels. After 5 nymphal #instars, the bug overwinters as adults. Authors Pekár, S., Hrušková, M. (2006) found that the #bugs use all three of their #senses to #recognize their #food: eyes, antennae, and labial sensillae.

Beetles go through stages called #instars as the newly hatched larva grows increasingly larger.
This Carrion Beetle (Silpha tristris) identified and filmed in #Brighton by @philipkarlbooker is likely to be the third final instar.
