There has been a noticeable drop in hoverflies this weekend bar the Eristalis, so the dopsy-turvey season is starting to wind down. The final blossoms have started in Japanese Knotweed, Michaelmas Daisy and even some early Ivy. August has seen Angelica well below par but Common Fleabane has been excellent. Over the weekend I visited Gilfach (west) [28 species], Caerau [28 species] and Garnwen (trig point) [22 species] Highlights included Dasysyrphus tricinctus, Rhingia rostrata, Eristalis intricaria, Helophilus hybridus, Pipiza austriaca and new for the year Volucella zonaria. The highest numbers recorded were by far Eristalis tenax (393).
