Brede High Wood

Holmans Meadow is a favourite place of mine to mooch about looking for wildlife, yesterday a fine selection of insects were found many of which have already featured this season on this site. I found a couple of species of hoverfly that were new to me, the scarce Rhingia rostrsata and the partial migrant Scaeva selenitica. R. rostrata is very similiar to Rhingia campestris which was very common on the reserve in May. Several features need to be checked to seperate the two species, a thin black line on the side of the abdomen and along the lateral margins of the tergites are a couple of features that are shown well when comparing the two species in the pictures below.
