The #dockbug #Coreus #marginatus (#Coreidae) is distributed from Europe to Asia. In #CentralEurope, it undergoes one generation per year, with the adults spending their #winter #diapause in hidden places. From October onwards, it can be found e.g. on the underside of #deadwood, as seen here in #Berlin's park Rehberge. T. O. Markova et al. (2020) did studies on the ecology of the #FarEast #subspecies C. m. orientalis.

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.

I finished this dock bug last week but haven't had a chance to take a decent photo of it until today. This is coloured pencil and ink over a base layer of watercolour. I hadn't accounted for how the pencil would interact with the rough grain of the paper, oops 😅 Next time I'll try using the smooth watercolour paper!
