North Cave Wetlands – 07/07/2019

An afternoon visit with sunny intervals and a light northerly breeze. Temperatures around 16 degrees C.

An interesting walk around the reserve with some cracking finds, the top three being Bembecia ichneumoniformis Six-belted Clearwing found around the Dragonfly Ponds, where there is plenty Bird’s-foot trefoil, the larval foodplant; plus two Crickets, Conocephalus dorsalis Short-winged Cone-head which appears to be new for the site, and Meconema thalassinum Oak Bush-cricket with only a single previous record from 2012. Other notable species included Glischrochilus hortensis, only the second time I’ve recorded this beetle, found adjacent to the Maize Field. First Erythromma viridulum Small Red-eyed Damselfly of the year was on the south side of Carp Lake, with my first Aeshna grandis Brown Hawker along the western path. Lepidoptera-wise Melanargia galathea Marbled White flew over the path to Turret Hide, with Dichrorampha petiverella Common Drill, Monochroa lucidella Buff-marked Neb and Stathmopoda pedella Alder Signal all good finds on the moth front. A few True Bugs were new for the year (NFY) with several adult Deraeocoris flavilinea noted, plus nymphs of Deraeocoris ruber. One adult Heterotoma planicornis was found, with several nymphs noted. Lygus rugulipennis European Tarnished Plant Bug was NFY along with a nymph of Phytocoris ulmi the first time I’ve found this latter species in this life stage. Finally to be confirmed was Scolopostethus cf. affinis, which will be a new species. Of note on the birding front was three juvenile Panurus biarmicus Bearded Tit on Reedbed Lake.
