The following series of photo's are of a crane fly larvae being attacked and killed by tiny leeches. This crane fly larvae is about three quarters of an inch long, it was dislodged from beneath a stone when I was taking pictures of caddis flies in a small spring trickle.

They begin attacking the exposed crane fly larvae.

As they attack the crane fly begins rolling over violently in an effort to shed the leaches. This is why it appears blurry.

More leeches arrive, joining the attack.

The whole struggle last only thirty seconds. The crane fly larvae is subdued, the leeches feed.
