The House Longhorn Hylotrupes bajulus is something I never thought I’d see. Until very recently, I thought it was a very rare indoor pest in a few houses breeding in old timbers, with only a single post-1970 dot in the cerambycid atlas. I’ve actually been contacted a couple of times with reports of possible House Longhorn infestations but they’ve turned out to be outdoor longhorns emerging from firewood.
So when I heard that House Longhorn could be seen outdoors, on some standing dead pines on a Surrey Heath, I thought I’d better mobilise and go to take a look. I was told that on a sunny day I’d be able to see them without having to peel any bark off, and so it proved on Sunday last weekend. I found one on the third tree I looked at, and saw three in total, all active in the sunshine.
I wish it well in its bid to colonise the British countryside.
