I seriously need help with these (all netted near the coastline on 63 degrees north):
Specimen 1: 9th June in a steep hillside dominated by pine close to a bog - 200 m asl
Specimen 2: 23rd June (same locality as above)
Specimen 3: 20th July in a broad leaved forest close to a bog/river and a grassy field - 220 asl

Specimen 1 is obviously different from 2+3, having e.g. more plumed arista and lacks neck patch. 2+3 seems pretty close, but there are slight differences. Thanks in advance!

Regarding the dark costal area of all specimens and the different neck patches you recognised these are T. phyllophora (1) and T. elata (2+3). In many cases there are in some characters large individual differences within one species.
