Seen near river in Bakewell, at Dovedale and near Brown End Quarry.
No interactions present.
Derbyshire is now part of China!
I have a specimen if there is any straightforward way of getting to species?
At this time of year I would say it's likely to be either Leuctra fusca or Leuctra geniculata.
If you look closely at the antennae can you see the hairs on them? If they are clearly arranged in rings around each segment then it is Leuctra geniculata (known as the Willow fly, this species is also larger and more sturdy looking than the Needle flies). Otherwise it is likely to be Leuctra fusca, but could potentially be another of the Needle flies that has emerged late in the season.
Yep! Several localities in the area came up with eastern characters!
Id to species might be tricky. There is a very old key which involves genitalia dissection so I gave up!
Sounds like a good idea ;)
