North Cave Wetlands – 11/07/2018

An overcast start in the morning, before brightening up in the afternoon. A gentle northerly breeze with temperatures reaching 20 degrees C. Several mature male Ruddy Darter Sympetrum sanguineum have suddenly appeared around the Dragonfly Ponds, which was a bit of a surprise, as no immature individuals had been observed on recent visits. Also a bit of drama from the Emperor Dragonfly Anax imperator on the eastern pond, where a territorial clash ended up with one male being downed onto the water. It struggled for several minutes, eventually making its way to the bank-side. After a few minutes it recovered its composure and flew of as if nothing had happened. Plenty of other activity around the dragonfly ponds with a further eight species noted, all listed at the foot of this post.

Ten species of butterflies recorded on this visit, nothing of note or out of the ordinary. Moths however were more obvious in the morning due to the overcast conditions. Bright Bell Eucosma hohenwartiana, Dingy Footman Eilema griseola and Timothy Tortrix Aphelia paleana all new for the year (NFY). Good numbers of Shaded Broad-bar Scotopteryx chenopodiata around Carp Lake, probably in to double figures. Six-spot Burnet Zygaena filipendulae was also abundant around the dragonfly ponds.
