Linacre 5th July 2025- A new Hoverfly!

 I had 2 hours down at Linacre yesterday morning. It was 18 degrees and overcast, but a few sunny spells enticed some butterflies out. I also had a new species of hoverfly and a bird species not recorded here since 2018!

The butterflies seen were: Ringlet (2), Meadow Brown (3), Gatekeeper (3, my first Linacre record of 2025), Comma (1) and, best of all, a single, pristine Painted Lady (my first of the year). 2 Common Blue Damselflies were also seen.

The new hoverfly was a very distinctive one, called Chrysotoxum bicinctum. See here for details. There were at least 2 on the vegetation by the overflow of the top reservoir. This is the second species of Chrysotoxum hoverfly I've seen at Linacre, the first being Chrysotoxum festivum, seen back in August 2016.

Birds seen were: Mallard (58), Tufted Duck (13), Mandarin (21; 20 adults and 1 duckling), Coot (18; 5 adults and 13 juveniles), Moorhen (0!!), Grey Heron (1), Grey Wagtail (3; 2 juveniles), Great-crested Grebe (12; 6 adults and 6 juveniles), Herring Gull (1 adult) and Lesser Black-backed Gull (3; 2 adults and a sub adult). 1 of the Lesser Black-backs was actively hunting the Mandarin duckling. 3 Chiffchaffs and 1 Blackcap were heard singing.

The most exciting species of bird was Crossbill, which, as I said, were the first record since 2018. Initially 3 birds were heard, and then seen briefly, landing in the Larch trees by the top reservoir. A further 8 (or most likely the some birds, plus 5 more) were seen flying over the ringing site. A great record, and hopefully the first of an "irruption year".
