Hello Libor and Theo,
thanks to you both! So it is not that easy as I thought...
I am no expert, but I experience here
Rhagio for many years. I know, size is not an argument and time of year may not be one, too. But I see the much bigger
R. scolopaceus males always here in May or beginning of June at other places, mostly fence stakes at meadows near hedges.
These smaller
Rhagio I see only in mid summer at shadowy places in the forest or at tree trunks in our garden. And they are
all much smaller than those flies in
spring. So most likely not the result of low diet of a few larvae. Generally, for my layman's eyes they are not the same animals...
Sorry that I do not collect animals, I am a photographer only.
