North Cave Wetlands – 21/10/2018

A mainly sunny morning, with light westerly breeze, temperatures reaching around 14 degrees C.

A challenging day on the invertebrate front, most species only getting going late morning. Several Common Darter Sympetrum striolatum present, mainly found along Dryham Lane. Two Migrant Hawker Aeshna mixta still active, both a male and female found today. Butterfly-wise a single Small Copper Lycaena phlaeas was all I could muster.

True Bugs were the main species group again. Two Corizus hyoscyami were found along Dryham Lane, the first time I’ve found more than one on a visit, though they are firmly now on the map here being recorded regularly on recent visits. Field Damsel Bug Nabis ferus was again found along the northern path. though they are very difficult to get close to for photographs. Gorse Shieldbug Piezodorus lituratus, Green Shieldbug Palomena prasina and Spiked Shieldbug Picromerus bidens were all found along the lane. Beetle-wise three species of Ladybirds noted:- 22-spot Ladybird Psyllobora vigintiduopunctata, 7-spot Ladybird Coccinella septempunctata and Harlequin Ladybird Harmonia axyridis.

Birding highlights included the Jack Snipe Lymnocryptes minimus, again in its favoured spot on Dryham Ings Cell C. Six Bearded Tit Panurus biarmicus dropped into the north side of Reedbed Lake. Marsh Harrier Circus aeruginosus was causing a commotion with several passes over Island Lake. Finally seven Whooper Swan Cygnus cygnus flew south, low over the reserve.
