North Cave Wetlands – 07/09/2018

A changeable morning with several showers and sunny spells, with a gentle to moderate westerly breeze blowing, temperature around 12 degrees C.

Conditions weren’t great for Dragonflies, though I did managed to find four species. An Emerald Damselfly Lestes sponsa was on the eastern Dragonfly Pond, with a single Ruddy Darter Sympetrum sanguineum nearby on the northern path. A few Common Darter Sympetrum striolatum were found around the reserve with several Common Blue Damselfly Enallagma cyathigerum eventually responding to a sunny spell, as I walked along Dryham Lane.

Four species of Butterfly on the wing, Small Copper Lycaena phlaeas the highlight with Large White Pieris brassicae, Small White Pieris rapae and Speckled Wood Pararge aegeria the others noted. Knot Grass Acronicta rumicis and Ruby Tiger Phragmatobia fuliginosa caterpillars were the only moth species found on this visit.

Six beetles recorded, two new species included Nebria brevicollis and Neocrepidodera transversa both along the northern path. A single Lagria hirta
was along the Maize Field path. 22-spot Ladybird Psyllobora vigintiduopunctata, 7-spot Ladybird Coccinella septempunctata and Harlequin Ladybird Harmonia axyridis making up the remainder.

Other invertebrates were hard to come by due to the showers, knocking the temperatures back and forcing them undercover, a few re-emerging when the sun came out. A sunny spell along the Maize Field path produced Field Grasshopper Chorthippus brunneus and a single Liocoris tripustulatus plant bug. Along the northern path Buff-tailed Bumblebee Bombus terrestris and Tachina fera were found before the first shower hit. Only two species of Hoverfly evident today with Eristalis tenax and Helophilus pendulus noted.

The reduced water levels on Island Lake are certainly to the liking of the Snipe Gallinago gallinago with nine present and showing well in the morning sun. Single Common Sandpiper Actitis hypoleucos and Green Sandpiper Tringa ochropus were also present, but distant, along with a Kingfisher Alcedo atthis. Canada Goose Branta canadensis numbers are starting to build with nine present on Dryham Ings Cell A where another Common Sandpiper A. hypoleucos and Green Sandpiper T. ochropus could also be found. Whilst in South Hide seven Curlew Numenius arquata dropped into Reedbed Lake.
