Trap Grounds Willow Emerald Update 22nd September

Lunchtime today at least 5 male Willow Emerald around the Swan pond at the Trap Grounds: 1 along the east side and 4 in the NW corner. All seemingly holding small territories which they defend from each other whilst waiting to snare a passing female. There were probably more but in breezy conditions they were a bit reclusive.

Also seen:
1 Southern Hawker
1 Migrant Hawker
Several "red" Darters

 

Trap Grounds update - 20 September

Again at least 6 Willow Emeralds; more likely 10+  . Swan Lake

Ovipositing observed for third day in a row - bodes well for next year!

LESSER EMPEROR - on Lake north of the Drayton to Sutton Courtenay Road - 26 August

Adrian Parr has just been in touch to point out that the apparently old or worn female Emperor, reported by Brian Walker on 26 August, was in fact a female Lesser Emperor!

This is the first record of Lesser Emperor in the county since 2011, and quite possibly the first record ever of a female!
