North Cave Wetlands – 17/06/2018

An overcast day with a gentle westerly breeze blowing, temperatures around 18 degrees C. The overcast conditions again kept the larger species in-active and therefore noticeable by their absence. A couple of Emperor Dragonfly Anax imperator were at the Dragonfly Ponds, with a female ovipositing in the eastern pond. Four-spotted Chaser Libellula quadrimaculata and Common Darter Sympetrum striolatum were the only others noted. Damselfly-wise Emerald Damselfly Lestes sponsa was new for the year (NFY), an immature male present at the start of the Butterfly Walk. Other species present included Azure Damselfly Coenagrion puella, Blue-tailed Damselfly Ischnura elegans, Common Blue Damselfly Enallagma cyathigerum and Red-eyed Damselfly Erythromma najas.

Butterflies were again subdued by the overcast conditions, though a Ringlet Aphantopus hyperantus was NFY. Common Blue Polyommatus icarus, Large Skipper Ochlodes sylvanus, Meadow Brown Maniola jurtina and Speckled Wood Pararge aegeria the only other species noted. Moth-wise Pea Moth Cydia nigricana was a new species for me, found along the western path, and a couple of Knot Grass Acronicta rumicis caterpillars were NFY. Other species recorded are listed at the bottom of the post.

On the Diptera front I set myself the challenge of finding as many of the Soldierflies species as I could, successfully finding Broad Centurion Chloromyia formosa, Common Green Colonel Oplodontha viridula, Common Orange Legionnaire Beris vallata (NFY), Four-barred Major Oxycera rara (NFY) and Flecked General Stratiomys singularior. Some allies of this group also found included Black Snipefly Chrysopilus cristatus, Stripe-legged Robberfly Dioctria baumhaueri (NFY) and Twin-lobed Deerfly Chrysops relictus. Several Stilt-legged Flies Micropeza corrigiolata were along the western path, this species determined by Ian Andrews, there seems to be very little general information available for this group of flies available.

Hoverfly-wise Chrysotoxum bicinctum, Eupeodes corollae and Syrphus ribesii were all NFY. It was also nice to find and photograph Xylota segnis which posed well on this occasion compared to previous visits. Full list for the visit at foot of the post.

The first Common Red Soldier Beetle Rhagonycha fulva was along the path to Turret Hide, the first of many, with Oedemera lurida also NFY.

The True Bugs have been noticeable by their absence on recent visits, however they are now starting to appear, with seven species noted. Capsus ater was a new species altogether for me, with Cuckoo-Spit Insect Philaenus spumarius, Grypocoris stysi and Nettle Groundbug Heterogaster urticae all NFY. Shieldbug nymphs are starting to appear with Blue Shieldbug Zicrona caerulea and Pied Shieldbug Tritomegas bicolor both noted. The final species recorded was Cercopis vulnerata.
