Thursday 1st June 2017:
Another warm afternoon saw me again visit Hillditch Pool to record the dragonflies. Today there were 4 Emperor Dragonflies (3♂ , 1♀) present, the female of which was seen oviposting (egg-laying). A single immature Scarce Chaser was also noted.

Another invert of note today was a bumblebee mimic hoverfly called Volucella bombylans. This hoverfly lays it's eggs in the nests of bumblebees and wasps where it's larvae will scavenge for food.

Saturday 3rd June 2017:
This afternoon I again decided to spend my time at Hillditch Pool. The weather was warm and sunny and a number of butterflies were on show including my first Meadow Brown of the year. Also observed were 2 Large Skippers, 1 Red Admiral and a ♂ Common Blue.
♂ Large Skipper (Ochlodes sylvanus)
There were 3 Emperor Dragonflies (2♂ , 1♀) present and also a ♂ Scarce Chaser. This was my first male of the latter species I had recorded at the site this year. Unlike the orange/brown female Scarce Chaser the male develops a powdery light blue colour (or pruinescence as its known) on it's abdomen.
