Can anyone identify this for me please it's the third one my dog has found on our shingle area in the last week?
Other information: We have a graden wall that is the retaining wall for a mill pond so we have a mill pond with about 2 feet of growth forming a border abour 12 feet above our heads in our back garden.
I am wondering if these are some kind of pond larvae that has strayed over the wall and fallen onto our shingle?
The size is genuinely between 1-1.25" long
Any help greatly appreciated.
Many thanks in advance
I'm fairly sure (I'd like to see the head better) you are seeing the larvae of great diving beetle, Dytiscus marginalis, commonly called water tigers.
Here's the adult
"Once the larvae grow to some size, they move to soil at the edge of water and burrow into a cell and pupate"
It seems your shingle is somewhat further away, so I don't know why they're appearing there.
...Unless certain dog is digging them up and dropping them there?
Having looked at the links you provided you are 100% spot on!
Thank you so much for solving this riddle for me. As they don't seem to be endangered I won't stop the dog when she finds them in future.
Once again thank you so much for your help on this one.
