North Cave Wetlands – 17/05/2018

A morning visit with intermittent sunny conditions, a gentle northerly breeze with temperatures around 12 degrees C. A good Dragonfly day with eight species recorded around the reserve. Hairy Dragonfly Brachytron pratense was new for the year (NFY), with two male present patrolling the reeds at the south side of Carp Lake looking for females to mate with. The presence of this species early in the season would indicate that it now has a foothold on site, though need to find an exuvia to confirm definite breeding. Lots of Red-eyed Damselfly Erythromma najas emerging from Carp Lake, many settling on the Brambles in the south-west corner. Now is the best time to see this species well, as soon as they have matured they will almost always be out over the water. Large Red Damselfly Pyrrhosoma nymphula now in to double figures. Previously this species has only been found as lone singletons, so another species showing positive signs of increasing. Of interest was a female of the colour form melanotum, the fist time I’ve found this colour form in Yorkshire. Azure Damselfly Coenagrion puella, Blue-tailed Damselfly Ischnura elegans and Common Blue Damselfly Enallagma cyathigerum all now in to three figures, the latter species more obvious around Carp Lake, with Azure Damselfly Coenagrion puella more prevalent along Dryham Lane. Broad-bodied Chaser Libellula depressa was only represented by a lone female in the north-west corner of Reedbed Lake, thought the northerly breeze was making conditions not ideal here. Finally a few Four-spotted Chaser Libellula quadrimaculata were noted around the reserve.

Butterfly-wise five species were noted, consisting of Green-veined White Pieris napi, Large White Pieris brassicae, Peacock Aglais io, Speckled Wood Pararge aegeria and Orange-tip Anthocharis cardamines. The latter species actually settling for a photo opportunity. On the moth front Silver Y Autographa gamma was (NFY), along with Common Nettle-tap Anthophila fabriciana (NFY) and Green Long-horn Adela reaumurella (NFY). The Garden Tiger Arctia caja caterpillars are now well grown and easily found around the reserve.

Another good day for Hoverflies, 13 species recorded. Tropidia scita and Xylota segnis were both NFY. An interesting observation with regards to the Parhelophilus sp. is the numbers present, probably into three figures along Dryham Lane, usually only encounter this species in single figures. Other noted include Cheilosia albitarsis agg, Cheilosia illustrata, Cheilosia variabilis, Epistrophe eligans, Eristalinus sepulchralis, Eristalis intricarius, Eristalis pertinax, Eupeodes sp, Helophilus hybridus, Helophilus pendulus and Leucozona lucorum.

Several Soldier Beetles are now evident with Cantharis cryptica (NFY), Cantharis livida (NFY) and Cantharis nigricans all noted. A Red-headed Cardinal Beetle Pyrochroa serraticornis was also (NFY). See list at bottom of page for other species.

Four Bumblebee species noted, again Vestal Cuckoo Bee Bombus vestalis seems to be having a good year with several found around the site. Other species included Buff-tailed Bumblebee Bombus terrestris, Common Carder Bee Bombus pascuorum and Large Red-tailed Bumblebee Bombus lapidarius.

Other miscellany included Panorpa communis (NFY) and Arge cyanocrocea (NFY), the latter being a new species to me.

Finally on to the birds. Hobby Falco subbuteo (NFY) was the highlight, one having an altercation with a Kestrel Falco tinnunculus along the western path. One of the Cetti’s Warbler Cettia cetti still remaining faithful to its Far lake territory. A single Dunlin Calidris alpina was on Cell A of Dryahma Ings.
