Linacre 8th July 2023 - a new species!!

I had news yesterday that the first Silver-washed Fritillaries and White-letter Hairstreaks of the year had been reported at Linacre (thanks  Pete). I set out this morning (6.15am - 9.15am) to see if I could spot either species. Unfortunately, the weather wasn't quite as good today (20 degrees, instead of 26 degrees yesterday), and the cloud cover was much higher, so I "dipped" on both species.

Luckily for me, however, I did manage to spot a new species of butterfly for Linacre - a female Dark Green Fritillary!! This species does seem to be on the increase in Derbyshire, and today's individual was spotted feeding on thistles in the hay meadow by the top reservoir.

Whilst there, I also spent some time in the field just beyond the top reservoir, where I spotted: Meadow Brown (c.10), Ringlet (c.5), Red Admiral (1), Large White (1), Small Skipper (3), Large Skipper (1), 2 Volucella pellucens (hoverfly) and a couple of 7-spot Ladybirds

Back on the top reservoir, the sun had come out again, and the number of damselflies had increased. Only two species were seen: Common Blue and Blue-tailed (first Linacre record of 2023), but both species were seen "in tandem", proving breeding. A Common Lizard was also seen by the top reservoir, but it was disturbed by 3 joggers (!!) before I could get a photo.

Hoverfly numbers were better today, with Volucella pellucens (2), a Sphaerophoria sp, Marmalade Hoverflies, and a Syrphus sp seen.

Last, and by no means least (!), were the birds. Waterbirds were: Mallard (147), Moorhen (19), Coot (24), Mandarin Duck (43), Tufted Duck (26), Grey Heron (1), Cormorant (1), Great-crested Grebe (13; 6 adults and 7 juveniles), Grey Wagtail (2; 1 adult and 1 juvenile), Lesser Black-backed Gull (1), Black-headed Gull (1 heard - an unusual July record), Little Grebe (1 adult heard), Buzzard (1), Chiffchaff (4 singing), Blackcap (3 birds seen and 3 heard),  Swallow (3), House Martin (3) and Swift (1 - my first Linacre record of 2023!!!).
