With all the Covid restrictions, it was a very slow year for Diptera recording. The Northants Diptera Group did not meet at all during the year, although individual members did do some recording on their local patches and a little more widely when restrictions were relaxed.
As mentioned in the April 2020 blog, the dotted bee-fly Bombylius discolor extended its range in Northants but I have had no further reports since the ones for Sywell Reservoir and the Daventry area.
With limited ability to get out, I worked through a lot of samples of flies taken in flight interception traps in 2018, and subsequently stored in alcohol. The traps had been set up primarily to find saproxylic beetles at Yardley Chase but I hoped some interesting saproxylic flies might also be present. Many of the specimens were in poor condition and not identifiable to species level and most of the ones I could identify were common species. However, one cranefly turned out to be Nationally Scarce - Rhipidia uniseriata. This is a saproxylic short-palped cranefly, family Limoniidae and this record is a county first. It was not in great condition but was clearly identifiable. The two attached photos show the key features.
