North Cave Wetlands – 05/05/2018

A warm sunny afternoon with a light westerly breeze, temperatures around 21 degrees C. First Odonata of the year (NFY) with Large Red Damselfly Pyrrhosoma nymphula (NFY) along Dryham Lane. Butterflies were very active in the warm weather, none settling long enough to photograph, even the Speckled Wood Pararge aegeria were settling with their wings closed to avoid the heat. Other species noted included Brimstone Gonepteryx rhamni, Green-veined White Pieris napi, Large White Pieris brassicae (NFY), Orange-tip Anthocharis cardamines, Peacock Aglais io and Small Tortoiseshell Aglais urticae. A Drinker Euthrix potatoria caterpillar was also found along the lane.

Eight species of Hoverfly recorded, the heat of the afternoon making it hard going, most hiding under leaves to escape the direct sun-light. Cheilosia variabilis (NFY), Epistrophe eligans, Eristalinus sepulchralis, Eristalis arbustorum, Eristalis pertinax, Helophilus pendulus, Leucozona lucorum and Rhingia campestris (NFY) making todays the list.

Beetle-wise Thistle Tortoise Beetle Cassida rubiginosa and Polydrusus cervinus were NFY along with an Amara sp. which I still need to try and key out, though they are a tricky genus to do.  22-spot Ladybird Psyllobora vigintiduopunctata, 7-spot Ladybird Coccinella septempunctata and Green Nettle Weevil Phyllobius pomaceus completing the list.

Only four species of Bees noted on this visit, Mining Bees noticeable by their absence, and Nomada Bees just too active to see well. Therefore only Bumblebees  made the list today with Common Carder Bee Bombus pascuorum, Large Red-tailed Bumblebee Bombus lapidarius, Small Garden Bumblebee Bombus hortorum and Vestal Cuckoo Bee Bombus vestalis all noted, the latter seeming a lot more obvious this year.

Other inverts. today included Blue Shieldbug Zicrona caerulea and Woundwort Shieldbug Eysarcoris venustissimus both NFY along the western path. A Slender Ground-hopper Tetrix subulata was also along the western path and a nice female Larinioides cornutus was found along the northern path.

Newts were very active in the Dragonfly Ponds with good numbers of Smooth Newt Lissotriton vulgaris showing well. Two Great Crested Newt Triturus cristatus also seen, one in the eastern pond the other one in the central pond, nice to see this species making a foothold on the reserve. Finally two Grass Snake Natrix helvetica (NFY) were along the western path bordering Far Lake.

Bird-wise the Cetti’s Warbler Cettia cetti made its presence known in the north-west corner of Reedbed Lake, showing briefly in the Brambles. A couple of NFY included Wheatear Oenanthe oenanthe in the north-west field, favouring the western edge of the un-ploughed section. The other was a couple of Whimbrel Numenius phaeopus which announced their presence whilst we were at the Dragonfly Ponds. A quick retrace of our steps found them in the north-east corner of Reedbed Lake, having a bit of a clean-up session. Common Sandpiper Actitis hypoleucos was on Cell A of Dryham Ings. Common Tern Sterna hirundo were active over the reserve favouring Main, Reedbed and Village Lake.
