Colin took this photograph of a female Brown Argus on 10/08/2017 at Lydlinch Common. Colin tells us that this species is not often seen at this site and knows this because he walks it regularly for Dorset Butterfly Conservation.
It is a very difficult butterfly to identify unless you have clear sightings of the unf, under fore-wing. The difference between this species and the Common Blue, which it can be mistaken for, is the lack of a black spot near the base of the unf. This is an excellent photograph as if there was a black spot present. it would be clearly visable.
Mark says: “Paid a short visit to Lydlinch Common this afternoon and despite the howling wind saw 5 Large Skipper, 5 Marsh Frits (including a mating pair), and a few other bits sent to the website. However the main event for me was just standing and listening to the uniquely beautiful song of a Nightingale singing its heart out (yes, they DO sing during daylight as well!) from the nearby undergrowth all the time I was there, absolutely amazing!”
A lovely shot from Tim, which gives a good idea of the butterfly’s size. It’s easy to assume all butterflies are the size of Red Admirals, but many are smaller. Tim found this friendly specimen at Lydlinch Common on 10 June.
Dave says: “Season starting to wind down now for the Marsh Frits with just a few seen, although this girl seemed quite fresh and egg laden. Also next year’s generation is on the way with this egg batch on the devils bit scabious”.
Thanks to Dave for this reminder that butterflies exist in more than their adult forms. How about you brilliant photographers sending us a few more photos of caterpillars and chrysalises?
Charles says: “Lydlinch common has an abundance of orchids at the moment and the Marsh Fritillaries are obviously happy to take a well earned rest on these beautiful plants. Photo taken on 4th June late afternoon.”
Lydlinch Common is in North Dorset, and together with other local sites hosts a very important number of this declining butterfly. Since 1976 we have seen a 79% decline in its occurence nationally.
