| A very rare Cryptocephalus beetle,
having RDB2 status and known from only a handful of UK
sites. Adult Cryptocephalus querceti have a
preference for feeding on the epicormic growth on
ancient/mature Oaks and are extremely similar to Cryptocephalus
labiatus. The elytral puncturation is much finer on querceti,
and although websites and literature often quote querceti
as having completely clear yellow legs, there is usually
some darkening of the hind femora. In labiatus,
the rear legs are usually completely dark, with at least
some degree of darkening on all other legs. C.
querceti also appears less short and bulky than labiatus,
even in the field and the females are larger (>3.5mm)
than the male. 1998 (Lott, D.) and 2010 (Alexander, K.) have provided the
only recent records from the Sherwood Forest NNR, until
we found C. querceti at Clipstone Old
Quarter in 2011. |
