Evidence of Large Tortoiseshell eggs & larvae has been found on Portland – the first time they have been detected wild in the UK for 70 years! Continue reading
Edmund sent us this photo of an Adonis Blue he took at Portland on 17/05/2020 adding the comment:
Not sure what it was doing with its proboscis extended on the Sedge stem. Finding something it liked no doubt.
Peter captured this photo of a Wall on 17/05/2020 at new ground on Portland. With its fast flashing flight and golden forewings this is another species that suggests it might be a fritillary but when seen at rest its bright eye spots confirm its identity as one of the browns.
Two more photos from Peter – the first one is a Dingy Skipper taken on 13/05/2020 at the High Angle Battery on Portland down the Old Railway cutting at the end of Park Road where Peter told us there were quite a few showing now. The second photo he took yesterday, 15/05/2020 on the old railway line, shows a pair of Common Blues which he thought may have been mating. He also mentioned that there were quite a lot of Small Blues there as well.
Peter has sent us these two photo’s he took at the High Angle Battery on Portland. The Small Copper is readily identified by its brightly burnished copper forewings with black margins and spots and the female is larger than the male which is highly territorial attacking any insect that comes close to it. The Small Copper photo was taken on 10/05/2020 and the Red Admiral on 07/05/2020.
Peter sent us two photos he took on 09/05/2020 at the old railway line at the end of Park Road, Portland. It is not often that we have such good photos of Small Blue and Common Blue side by side for comparison, which can be very helpful.
When Mike visited Portland on 21/07/19 he witnessed these Chalkhill Blues having a party! They certainly look like they are enjoying the drinks, in this instance minerals from the small rock they have alighted on. Continue reading
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.
MIchelle saw this Adonis Blue and Hummingbird Hawkmoth at Westcliff, Portland on 21/06/19 and 31/05/19 respectively.
Both species are enjoying Red Valerian flowers, a favourite and easy to grow plant for butterflies and moths to nectar on.
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.
