North Cave Wetlands – 17/09/2017

A morning visit, misty at first before brightening up and then clouding over. Gentle northerly breeze blowing. Migrant Hawker Aeshna mixta and Common Darter Sympetrum striolatum were around in expected numbers for the time of the year, with several Common Blue Damselfly Enallagma cyathigerum easily encountered. A Blue-tailed Damselfly Ischnura elegans was also found on the western dragonfly pond.

Red Admiral Vanessa atalanta were showing well, making full use of the flowering Ivy along the northern path. Comma Polygonia c-album, Green-veined White Pieris napi and Speckled Wood Pararge aegeria also noted.

Another good True Bug day, this time of year being the best time to catch up with our Shieldbug species. Woundwort Shieldbug Eysarcoris venustissimus, Gorse Shieldbug Piezodorus lituratus and Spiked Shieldbug Picromerus bidens all noted as I walked the site. Other species included Common Froghopper Philaenus spumarius, Eupteryx aurata, Marsh Damselbug Nabis limbatus and a Lygus sp.

On the Beetle front Nebria salina was a new species for me, close examination of the hind tarsus for presence of hairs needed to rule out other species. 7-spot Ladybird Coccinella septempunctata are now back on the agenda after some recent no shows, along with Harlequin Ladybird Harmonia axyridis.

Other miscellany included a female Lesser Marsh Grasshopper Chorthippus albomarginatus, the white stripe along the wing making separation from Meadow Grasshopper Chorthippus parallelus straight forward. Plenty of Honey Bee Apis mellifera were on the Ivy, along with a few Eristalis tenax. Finally a Scorpianfly Panorpa communis showed well enough to get it to species level.
