Fiona McGillivray sent us this great photo of a larvae she found in the sand at Ardnave. This was her description:
The nearest I can pin it down to is a type of wireworm but it is not like any
others I have come across, it is more snake like in behaviour than a worm, very
mobile, particularly in warm conditions, seeks out the dark/cover of the sand or
roots it is near. It does appear to have a head (black and triangular), c.18
segments but it also seems to be just as sensitive and mobile from the other end
too. It was
living in the sand, not dung. This one was about 30mm long, the other I saw
before was smaller.
Thanks for the photo, Fiona. If anyone knows what it is, please let us know!
