North Cave Wetlands – 04/05/2017

An afternoon visit following a morning sojourn to nearby North Cliffe Wood. Similar weather condition though the wind seemed to change to a more easterly direction. Common Blue Damselfly Enallagma cyathigerum now emerging in numbers with several found around Carp Lake. Only other species noted was a single Large Red Damselfly Pyrrhosoma nymphula. On the butterfly front it appears to be a good year for Orange-tip Anthocharis cardamines with a healthy number present on site. Usually a hard species to find settled for that photo opportunity, though they all seemed so amenable on this occasion. Only other species recorded were Green-veined White Pieris napi and Peacock Inachis io.

With Green Nettle Weevil Phyllobius pomaceus now abundant on the nettles they are now joined by their smaller relatives Small Green Nettle Weevil Phyllobius roboretanus. Care needs to be taken with the latter species to rule out the very similar Phyllobius virideaeris which is also on site. A quick check underneath will confirm their ID, dark underneath on the former, with the latter having the green scales underneath as well as on top. A couple of similar Polydrusus cervinus were also present. A couple of beetle associated with the willow were located, but still to be confirmed; Blue Willow Beetle Phratora cf. vulgatissima and Crepidodera cf. plutus. Usual ladybird species present, but still no sign of Adonis’ Ladybird Hippodamia variegata so far this year.

On the Hoverfly front it was nice to find Xylota segnis, a new site record for me. Other species noted included Rhingia campestris, Helophilus pendulus, Eristalis intricarius, Platycheirus scutatus agg, Epistrophe eligans, Leucozona lucorum, Eristalis pertinax, Eristalinus sepulchralis, Myathropa florea and Baccha elongata. A couple of flies found included the impressive Tachina fera and one of the hard to identify Myopa species, possibly Myopa tessellatipennis.

Finally on the invertebrate front a couple of Nomad Bees, Marsham’s Nomad Bee Nomada marshamella and Nomada Flava agg. First Woundwort Shieldbugs Eysarcoris venustissimus were near the gate at the south-west corner of Carp Lake, along with several Cercopis vulnerata. A Slender Groundhopper Tetrix subulata was on the Brambles along the west path.

Last but not least the birds, with a nice selection of waders on Dryham Ings Cell A. Present here were Bar-tailed Godwit Limosa lapponica, Dunlin Calidris alpina, Common Sandpiper Actitis hypoleucos, Ruff Philomachus pugnax, Little Ringed Plover Charadrius dubius and Avocet Recurvirostra avosetta. Mediterranean Gulls Larus melanocephalus were on Main Lake and a showy Sedge Warbler Acrocephalus schoenobaenus was singing on the west side of Carp Lake along with a few Blackcap Sylvia atricapilla.
