This Speckled Longhorn (Pachytodes cerambyciformis) was feeding on Ground Elder (Aegopodium podagraria), which is flowering in abundance next to the Neath Canal, near Glyn-neath, today. Only the second time I've seen this species and, interestingly, the first sighting was made almost exactly 2 years ago, on 20th June 2011. On that day I found the Speckled Longhorn, with other species of Longhorn, feeding on Hemlock Water-dropwort (Oenanthe crocata) next to the Neath Canal, near Tonna. It would appear to be a good time to look for this attractive beetle, and checking umbellifers along the Neath Canal seems to be as good a place as any to find it.
The memorable Longhorn day at Tonna, from 2 years ago, was also illustrated in a post on this blog and can be found HERE
