Dusking on the Dunes

I had a pleasant hour yesterday evening (26/5)  with a sweep net on the dunes and upper saltmarsh at the North Dock (Llanelli) dunes LNR. The highlight was the presence of quite a decent number of grass eggar caterpillars, swept from coarse vegetation.  Plenty of the little white Elachista argentella and several green carpets were also noted. Several Crambus lathoniellus were netted and a single Aspilapterix tringipennella.

                                           Above: the grass-moth Crambus lathoniellus.
Above: for those who are interested, Acrosanthe (Thereva) annulata, a duneland stilleto-fly in this part of the world. The much rarer (browner and larger) Thereva cinifera also occurs on the North Dock dunes LNR.
