Paul had a good day at Ballard Down on 29/04/2019. He was one of two people who reported first sightings of a Common Blue on the day, and he tells us that he saw 20 to 30 Wall Browns at Ballard and Durlston – great news!

Alison photographed this female Common Blue at Worth Matravers on 6/08/18.

The red mites are trombidium breei, and although they look unpleasant, do not apparently harm the butterfly.They are also found on other species such as Marbled Whites, Meadow Browns, and Small Skippers to name a few of long grassland species affected.

Andy tells us on 2/11/18 at Southbourne Undercliffe, the temperature was 14c and sunny when he saw this Common Blue along with lots of Clouded Yellows, a Red Admiral, a Small Copper and Small and Large Whites.

Quite amazing to see this many species in early November.

Penny found this lovely male Common Blue at Portland on 6/09/18.

It looks in such a pristine condition, so it is hard to believe we are already into Autumn. The Blues seem to have had a very good year and after the prolonged dry spell, the rains have revived the caterpillar foodplants . Hopefully this will ode well for the 2019 butterfly season.

Harold went on a guided walk to Ballard Down on 19/08/18 and photographed this Common Blue.

Sadly the weather was not good, and only one other person turned up, which was a pity asit  brightened up later and a few butterflies were seen.

This female Common Blue is lovely and it shows how variable the females can be. Often the upperwing ground colour is brown with blue basal and discal shading, but on this specimen the blue is very extensive.

Brian was surprised to see this Common Blue nectaring on Monbretia flowers in his Harman’s Cross garden on 13/09/18.

He commented that he has never seen any butterflies using it before in all the years he has lived there, yet he also found a Tortoiseshell nectaring on it too.The first butterfly he saw on the flowers the day before, he had thought was taking moisture from the leaves after the rain the previous night.

As Brian also remarked, the blue of the subject against the rich orange flowers made for a stunning photograph.

MIchael photographed this beautiful Male Common Blue on Bournemouth Cliffs on 28/07/18.

This butterfly’s wings are almost transparent as you can see through them to the flower buds it is nectaring on.

Common Blues appear to be having a good year as there are numerous reports of good numbers being seen in gardens as well as the wider countryside.
