Another sighting of a Large Tortoiseshell on Portland ,but this time near Fancy’s Farm. Andrew saw this one on 10/07/19 and tells us it was nectaring on Buddleia for quite a while before flying off.

This one looks very fresh and surely cannot be one of the two seen so much earlier this year. After the mixture of wet, windy, then hot ,dry weather , it would by now be looking a little frayed around the edges if it had been around since February.

Adonis Blue Caterpillar, Portland

Michelle found this small Adonis Blue caterpillar at Westcliff on 24/06/19.

The larvae are green with yellow stripes running along the length of the body. Unlike its close relative, the Chalkhill Blue, the larva of the Adonis Blue feeds by day. The larva has a Newcomer’s gland in the 7th segment which provides secretions that are attractive to ants. This is a symbiotic relationship for, like many other blues, the Adonis Blue larva (and pupa) is afforded protection by the ants from parasites and other predators.

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.
