Chrysolina oricalcia (Müller, O.F., 1776)
Chrysolina oricalcia is one of a range of leaf beetles belonging to the Chrysomelidae group, with the most well known member being the infamous Colorado Beetle. This seems to be a common species where it occurs, but we have only found it occasionally on Cow Parsley in a few areas of Sherwood Forest. We have recorded it once during the Winter months, on a mild late November evening in 2008, when one was found at the base of a tree during a moth trapping session. Despite being just under 10mm in length, this is an easy species to spot on the stems of Cow Parsley and comes in two colour forms, both of which are shown below. This beetle is classed as Nb (Nationally Scarce Grade B. Recorded in 31-100 10km squares since 1980)
