I managed to fit a profitable collecting day into a visit to friends in Somerset. On a trip to some pools and ditches near Kingston Seymour I encountered very large numbers of Helophilus trivittatus and two Epsitrophe diaphana. I don't think I have ever seen so may H trivittatus at once - there were possibly hundreds around a small area of pools, feasting on Hemlock Water Dropwort, along with thousands of other flies - lots of Eristalis spp in particular.

So, it's probably worth watching out for E diaphana - which can very easily be mistaken for the much commoner E grossulariae, but as a useful "field alert" it does appear to be more orange yellow than that species. I don't think most of us would overlook H trivittatus - it's such a flash and big beast!
