Alder Leaf Beetle Agelastica alni (Linnaeus, 1758)
A rare beetle which was previously believed to be extinct in the UK. However, there have been recent records and the true status of Agelastica alni, is currently unknown and has RDB K (Insufficiently known) status. Commonly known as the Alder Leaf Beetle, Agelastica alni was once believed to have migrant tendancies.

It is an obvious species when seen, measuring around 7mm in length. Its appearence on several small Alders growing on Warsop Main Pit Top in September 2014, was surprising. There were believed to be no previous county records, but this beetle had been recorded at Dyscarr Wood in north Nottinghamshire by Pauline Bradford on June 11th 2014. Recorded from Shireoaks Pit Top in April 2015
(Toplis, C.).
