I suppose many have noticed the masses of hoverflies around in the last couple of weeks. Good time of the year to get a few additions to the year list and we had a good variety of species without trying too hard on Saturday at Tophill Low NR, East Yorks.
A selection of pictures taken by Doug Fairweather and myself.
Episyrphus balteatus is by the far the most obvious but looking a little harder turns up a variety.
And once in a while the scarcer Helophilus trivittatus can be found, albeit only two records of this solitary, migrant species have been noted. The bad photo below is from 2008 and one in July 2011 didn't linger long enough for the 'dipteria paperazzi' to take a picture!
The other Tophill highlight was a late Agapanthia villosoviridescens down the south end. They don't look quite as good as they did in May!
