Castle Water

19th March 2012, Monday

Highlights from a day at Castle Water included Firecrest, 2 Raven, Common Buzzard, 3 Marsh Harrier and 10 Avocet, insects on the wing included 2 Small Tortoiseshell, Common Carder Bee, Buff and White-tailed Bumblebee, and at least 6 of each Common Bee-fly and the hoverfly Cheilosia grossa. This distinctive early hoverfly can be seen around the short grassy areas near the viewpoint flying low to the ground as it searches out its host plants, in this case young Spear Thistles.
