Western Conifer Seed Bug Leptoglossus occidentalis (Heidemann, 1910)
The Western Conifer Seed Bug is a large North American species. It was recorded in Europe (Italy) in 1999, possibly via imported timber and has since spread rapidly, appearing in the UK for the first time in 2007 at Weymouth College (Ford, B.) There were further records during the latter part of 2008, with most records coming from MV moth traps operated along the south and south-east coasts. Adults even reached inland, with the most northerly being at Kendal (Petley-Jones, R.) Nearer to Nottinghamshire, there were records from Quorn in Leicestershire (Gamble, P.) and at Charlesworth in Derbyshire (recorder unknown) There have recently been more reports of this bug at MV light since early September 2009. This adult however, appears to be the first Nottinghamshire record. It was found by Mrs Moira Worthington at Eakring, on the bedroom curtains on September 27th 2009. Thankfully, she emailed a picture to us for identification and retained the specimen.

The Western Conifer Seed Bug is a Nearctic pest of conifer seed nurseries and records currently have to be sent to DEFRA. There are no records of this bug breeding in the wild state as yet, but this is considered to be very likely, due to it's rapid colonistation and spread across Europe within ten years.
