Video at the end is about Freshwater Hoglouse.

Harlequin Ladybirds that had to be removed from hibernation at work (154 in total). I found three forms. The commonest f.succinea (0-21 spots), f.spectabilis (Black with 4 spots) and f.conspicua (Black with 2 spots). None of the form acyridis (Black with 21 Red spots).
Introduced to Europe as a pest control, reached Britain in 2004. Out compete native species by feeding 4x faster. Considered the most invasive ladybird in the world.
