Hi Felix - the only thing I can think of ... is that this critter is part of a mark-and-recapture exercise.
Cheers,
- Pete

Hi Mr T.
This brown argus...
Looks like ab.
pallida, the lunules are creamy yellow rather than orange. That's a very nice find.
Did you notice the
burnet moth larva diving for cover in
this one?
I am unable to critique your pictures Felix, as I am not a photographer, but they certainly make me impatient for the coming season..!
Felix.

Thanks for that Felix I am very suprised that I found that Brown Agus aberration with no idea I found it

. Just out of intrest how rare do you think it is to find that abberation?
Yes I did notice that caterpiller there and wondered what it was, I was just seeing if anyone would notice with the camoflague it has which show the eagle eyes we have!
Also thanks for the comment on my pictures very uplifting
From a happy
Felix

Difficult to say, Felix.
It could crop up anywhere, but will never crop up in colonies where the gene responsible is not present, unless of course the gene is introduced by a vagrant butterfly from another population.
It is always worth looking again in populations where the aberration has been observed previously, and if the colony is small and relatively isolated your chances of seeing it again are increased.
Happy hunting.
Felix.
