North Cave Wetlands – 30/04/2017

A sunny morning visit with a strong south-easterly breeze blowing, most of the invertebrates sheltering along the western path. First Common Blue Damselfly Enallagma cyathigerum of the year was found along the western path, shouldn’t be too long before the masses start to emerge. Several butterflies around with Large White Pieris brassicae another first for the year. Orange-tip Anthocharis cardamines, Green-veined White Pieris napi and Peacock Inachis io the other species logged.

A few bees noted included a new reserve record for me in the shape of Marsham’s Nomad Bee Nomada marshamella, along with a first for the year Chocolate Mining Bee Andrena scotica. Records again all logged on iRecord and IDs already confirmed. Common Carder Bee Bombus pascuorum was the only other species recorded on this visit.

Plenty of hoverflies around now, so was hoping for something new. Wasn’t disappointed as the following were all new species to me; Dasysyrphus albostriatus, Melanostoma mellinum and a Pipiza sp. which would need microscopic determination. Thanks go to Ian Andrews with the helpful feedback he leaves on my Flickr site. Other species noted on this visit in no particular order included Rhingia campestris, Leucozona lucorum, Epistrophe eligans, Eristalis pertinax, Eristalis intricarius, Helophilus hybridus, Cheilosia variabilis, Cheilosia illustrata, Platycheirus albimanus, Syrphus sp. and Cheilosia cf. proxima, the latter not fully determined to species level. A couple of other attractive flies included Euleia heraclei and Mesembrina meridiana.

A few beetles photographed included 7-spot Ladybird Coccinella 7-punctata, 14-spot Ladybird Propylea quattuordecimpunctata, Thistle Tortoise Beetle Cassida rubiginosa, Pea-leaf Weevil Sitona lineatus and Cereal Leaf Beetle Oulema melanopus s.l. plus a couple of species that couldn’t be fully determined, Apionidae and Elateridae. Next few weeks should see the start of Soldier Beetle and Longhorn Beetle season, and hopefully the appearance of the Adonis’ Ladybird Hippodamia variegata.

A few other miscellaneous bits and pieces included the first Cercopis vulnerata at the south-west corner of Far Lake, which seems to be their favoured area. A Cucumber Spider Araniella cucurbitina sensu lato was found along the western path.

On the birding front it was a bit of a black day, with 13 Black Tern Chlidonias niger on Village Lake making an impressive sight. Four Common Tern Sterna hirundo were also present on Village Lake. At least three Mediterranean Gull Larus melanocephalus on site, all in their favoured spots. Several Ruff Calidris pugnax on various parts of the reserve and a Black-tailed Godwit Limosa limosa on Reedbed Lake.
