THE SQUASH BUG COREUS MARGINATUS
IN WORCESTERSHIRE
John Meiklejohn
This large bug is said to be restricted to the southern half of
England and Wales being quite common in the southern counties. It
is found in Worcestershire with more records from the South than
from the North of the county. The common name derives from it
being a pest on squash crops in North America. In Britain it is
found in a wide range of reasonably open habitats where it feeds
on docks, knotweeds, sorrel and Persicarias. Later in the year
the adults can be found feeding on blackberries and other seed
heads before going into hibernation.
Does the northern boundary of its distribution in Britain pass
through Worcestershire? We need more records to find out so
please keep a look out for this bug and send your records to me
at the WBRC office.
The adult bug is red-brown in colour, often very dark, 14-15 mms
long and looking like a large Shield Bug. On the head between the
bases of the antennae there are two small but distinct horns. The
antennae have only four segments, the Shield Bugs have five.
