North Cave Wetlands – 26/09/2017

Temperatures in the high teens with intermittent sun, gentle easterly breeze blowing. Good numbers of Migrant Hawker Aeshna mixta around the site, posing well for the camera, including an ovipositing female at the dragonfly ponds. Common Darter Sympetrum striolatum also well represented with several mating pairs noted. Common Blue Damselfly Enallagma cyathigerum now easily counted as their season is almost over, only four individuals noted. Nice to find a Ruddy Darter Sympetrum sanguineum at the eastern Dragonfly Pond, this being the latest site record for me by almost three weeks.

Butterflies were in short supply, only a couple of Red Admiral Vanessa atalanta noted, along with a single Green-veined White Pieris napi. A nice Knot Grass Acronicta rumicis moth caterpillar was a nice find, plenty of Nettle-Tap Anthophila fabriciana the only other moth species logged.

Hawthorn Shieldbug Acanthosoma haemorrhoidale added a bit of variety to the recent run of Shieldbugs, with a couple of Gorse Shieldbug Piezodorus lituratus showing well along Dryham Lane adjacent to Village Lake. Several Green Shieldbug Palomena prasina noted at various points around the reserve, plus a single Woundwort Shieldbug Eysarcoris venustissimus. A new Groundbug in the shape of Cymus claviculus was a first for me, bit of a challenge to photograph being only 4mm in length. Finally a Lygus sp. was along the western path.

Other miscellany included a couple of Spiders, Nursery Web Spider Pisaura mirabilis and a Tetragnathidae sp. An Ichneumon species was photographed at the start of the Butterfly Walk, this is a tricky group, but believe this is Achaius oratorius. A Field Grasshopper Chorthippus brunneus was photographed along Dryham Lane. Finally four Common Lizard Zootoca vivipara were seen and photographed along the northern path. Two individuals had lost their tails, which is a defensive measure when attacked, these will grow back.
