Arhopalus rusticus
Another of the longhorn beetles, Arhopalus rusticus is the largest species (around 25mm long) we have come across to date. There have been several Eakring records of this mahogany coloured beetle, all involving adults which came to the light of an MV moth trap at Lound Wood. The larva live in both standing and fallen trunks/stumps of conifers and take up to 2 years to become fully grown. Arhopalus rusticus is largely nocturnal and often hides under bark by day, but is most often seen when attracted to light after dark. Originally a Scottish species, this beetle has spread widely with the widescale use of conifer plantations across England in recent years.
