Went out for an excellent day of entomology with Trstan Bantock (http://britishbugs.org.uk/) today.
Hartslock turned up the usual things but I did find a very nice Exorista which looks like larvarum at first glance. Butterflies were fairly good with a few unusually small Small Heaths and a good number of Adonis Blues plus a female Chalk-hill Blue and a few Brown Argus and Common Blues. The weather turned a bit cloudy and windy so we got in the car and head-off for Warburg, near Henley-on-Thames.
Warburg was bathed in sunshine and the main ride (The Range) was alive with Diptera of all kinds. The commonest by far was Tachina fera, again, but Sturmia bella was also very common. Chiltern & Autumn Gentians were in full flower but the umbellifers look to be going over.
