North Cave Wetlands – 09/04/2017

A warm afternoon, temperatures reaching around 20 degrees, with a moderate westerly breeze blowing. Several species of butterfly now on the wing around the wetlands, with Green-veined White Pieris napi being the most numerous. Orange-tip Anthocharis cardamines, Brimstone Gonepteryx rhamni, Peacock Inachis io and Small Tortosieshell Aglais urticae being the others. A search for ladybird species, found plenty of 7 Spot Ladybird Coccinella 7-punctata, with a couple of 22 Spot Ladybird Psyllobora vigintiduopunctata being added to the year list. Another couple of beetles found included three Thistle Tortoise Beetles Cassida rubiginosa and the attractive Chrysolina polita. Was hoping that the warmer weather would increase the numbers of hoverflies, however only a couple were found, Eristalis pertinax and Eristalis intricarius. A Slender Ground-hopper Tetrix subulata was found along Dryham Lane.

On the birding front a Black-tailed Godwit Limosa limosa was on Village Lake, along with the 2nd summer Mediterranean Gull Larus melanocephalus. A couple of Ruff Philomachus pugnax and a Little Ringed Plover Charadrius dubius were on Cell A, Dryham Ings. An interesting hybrid between Mallard Anus platyrhynchos and Gadwall Anas strepera was also on Cell A, a regular hybrid known as Brewer’s Duck.
