Darters at Ditchford

A curious Common Darter

Male Ruddy Darter with the blood-red body.

We are now in the cross-over time between the summer species and the first appearence of the autumn species. The number of Common Blue Damselflies at Ditchford have plummeted from a peak of 500+ to ~100. Emperors are declining and Brown Hawker are ascending. We saw many oviposting Brown Hawker which is typical for this time of year. A few Migrant Hawker exuviae were found including one make with damaged wings. A single Ruddy Darter and a few Common Darter were also around.
