North Cave Wetlands – 07/06/2018

An overcast start to the afternoon, before brightening up. A gentle northerly breeze with temperatures around 18 degrees C. Three new for year (NFY) species noted on the dragonfly front with Emperor Dragonfly Anax imperator showing well with a female ovipositing in the western Dragonfly Pond, along with double figures of exuvia noted on the eastern Dragonfly Pond. Black-tailed Skimmer Orthetrum cancellatum were also present, with breeding activity noted around the western pond. A single fresh Common Darter Sympetrum striolatum also made its first flight from the dragonfly ponds. A single male Hairy Dragonfly Brachytron pratense was on the eastern dragonfly pond, along with good numbers of Four-spotted Chaser Libellula quadrimaculata also present around the reserve. The Damselflies are now more active around water now they’ve matured, especially the Red-eyed Damselfly Erythromma najas which are out over Carp and Far Lake, only a single female being found in the surrounding grasses. A pair of Large Red Damselfly Pyrrhosoma nymphula were in tandem around the western pond. Azure Damselfly Coenagrion puella, Blue-tailed Damselfly Ischnura elegans and Common Blue Damselfly Enallagma cyathigerum all noted in good numbers.

Butterfly-wise Large Skipper Ochlodes sylvanus, Common Blue Polyommatus icarus, Meadow Brown Maniola jurtina and Red Admiral Vanessa atalanta were all NFY. Smaller numbers of whites now, as we head to the lull between broods, a single Green-veined White Pieris napi the only representative of the first brood. A single Orange-tip Anthocharis cardamines could well be the last I see this year, as their season is almost over. Speckled Wood Pararge aegeria are multiple brooded and it appeared that a recent emergence had taken place, as most were in good condition. A couple of Brimstone Gonepteryx rhamni were still around, these most likely the last of the over-wintering adults.

A few moths also noted on this visit. Several Yellow-barred Long-horn Nemophora degeerella (NFY) were along Dryham Lane in small clusters. Red Piercer Lathronympha strigana (NFY) was a new species altogether for me, again along Dryham Lane. Common Marble Celypha lacunana, Garden Grass-veneer Chrysoteuchia culmella, Silver-ground Carpet Xanthorhoe montanata and Yellow Shell Camptogramma bilineata were all NFY. Several Silver Y Autographa gamma also noted around the reserve. A nice caterpillar of Yellow-tail Euproctis similis was found along the western path near Far Lake.

Beetle-wise Polydrusus formosus, one of the green weevils was NFY and also new to me, so a nice find. Golden-bloomed Grey Longhorn Beetle Agapanthia villosoviridescens was NFY and always nice to find, one of Longhorn group of beetles. Other species noted included Harlequin Ladybird Harmonia axyridis, 7-spot Ladybird Coccinella septempunctata, Wasp Beetle Clytus arietis, Cantharis livida and Cantharis nigricans.

A few Solderflies and their Allies were noted on this visit, Flecked General Stratiomys singularior (NFY) being the best of the bunch with several noted around the south side of Carp Lake. One or two Broad Centurion Chloromyia formosa (NFY) are also now present around the reserve. June is the time off year to start being aware of the biting fraternity, with Black-horned Cleg Haematopota crassicornis (NFY) and Twin-lobed Deerfly Chrysops relictus (NFY) now on the wing, making their presence felt! Downlooker Snipefly Rhagio scolopaceus was (NFY) and a new reserve tick with the final species being Striped Slender Robberfly Leptogaster cylindrica (NFY).

On the hoverfly front, a new species to me, and as far as I’m aware, a new species for the reserve was Platycheirus rosarum (NFY) found along Dryham Lane. Other species recorded included Eristalinus sepulchralis, Eristalis arbustorum, Helophilus pendulus, Myathropa florea, Parhelophilus sp, Tropidia scita, Volucella bombylans and Volucella pellucens.
