NORWICH: Snout & oak gall

6th September 2017

A couple of interesting observations from Lakenham before work on Wednesday. Firstly I spotted a Snout moth resting in a hedge, a common moth this time of year but more often seen amongst the vegetation so sometimes hard to photograph. Secondly on Lakenham Way I saw a gall caused by the gall wasp Andricus grossulariae on Oak. The life cycle of this species, along with some other gall wasps, is a bit unusual. There is a sexual generation that produces small red galls on Turkey Oak catkins, but also an asexual generation that gives rise to the gall I saw today (a sort of frizzy knopper gall).
