North Cave Wetlands – 14/08/2018

An overcast afternoon visit, with a gentle westerly breeze, temperatures around 20 degrees C. A quiet day for invertebrates on the whole with a couple of nice observations. On the Dragonfly front only four species noted. Migrant Hawker Aeshna mixta and Common Darter Sympetrum striolatum representing the larger species, both likely to be around for another couple of months. Interesting to still be finding teneral Blue-tailed Damselfly Ischnura elegans and to a lesser extent Common Blue Damselfly Enallagma cyathigerum, both likely to be around well into September.

Quiet on the Butterfly front, with only Green-veined White Pieris napi, Painted Lady Vanessa cardui, Red Admiral Vanessa atalanta and Speckled Wood Pararge aegeria recorded.

Beetle-wise seven species present, including 14-spot Ladybird Propylea quattuordecimpunctata, 22-spot Ladybird Psyllobora vigintiduopunctata, 7-spot Ladybird Coccinella septempunctata, Adonis’ Ladybird Hippodamia variegata and Harlequin Ladybird Harmonia axyridis, number much reduced along the Maize Field path compared to the last visit. Alder Leaf Beetle Agelastica alni still present at Far Lake in the western path view point. A Thistle Tortoise Beetle Cassida rubiginosa was also found along the northern path.

Hoverflies were very much noticable by their absence, though Meliscaeva cinctella (NFY) was a nice find and possibly a new species for the reserve. The only other species note were Marmalade Hoverfly Episyrphus balteatus, Eristalis tenax and a male Sphaerophoria scripta.

A few True Bugs found Marsh Damselbug Nabis limbatus (NFY) at the south side of Carp Lake. A Green Shieldbug Palomena prasina nymph was found along the Western Path. Good numbers of Common Froghopper Philaenus spumarius were along Dryham Lane.

Lesser Marsh Grasshopper Chorthippus albomarginatus appears to be the most abundant Grasshopper present on the reserve this year.

Finally a few birds of note included four Common Sandpiper Actitis hypoleucos on Dryham Ings Cell A, with another bird on Island Lake. Other birds on Cell A included a Green Sandpiper Tringa ochropus along with several Little Egret Egretta garzetta showing well from Crosslands Hide. A single Pink-footed Goose Anser brachyrhynchus was on Island Lake. The attractive Black Swan Cygnus atratus showed well on Main Lake, nice to see, though not officially countable as a wild bird.
