I have just had some interesting information from Adrian Parr (the BDS Migrant Dragonfly expert) about this year's the ongoing Red-veined Darter influx:
"The RVD influx continues, and I've just heard of counts of 120 + 95 on two of the lakes on Bodmin Moor!! There have been over 470 records (though from slightly fewer sites) this year. I think it's now fair to say it's been Britain's largest ever influx.
Keep an eye out for locally bred immatures, which may start emerging as early as late July. Such individuals rapidly stray from their breeding waters into surrounding grassland, and then ultimately migrate back south.
But virtually nothing is known about the fine detail of all this, and I'm hopeful someone might keep a close eye on one of their breeding sites this year."
