Other: The Two-spot Ladybug is one of Alberta's
more common and easily recognizable Ladybugs. It is a tree dwelling
species that is commonly found on Mountain Ash, Weeping Birch, Wolf Willow
and Caragana. It's primary reason for being there is to hunt aphids.
The black markings on the Two-spot Ladybug's elytra are highly variable.
Different variations include 2 large black spots, 4 small spots in a row, 2
bands and 10 spots. Across all of these variations is a central
M-shaped mark on the pronotum with black dots in the middle of the pale
areas on either side. As winter approaches the two-spot moves into
sheltered places, such as buildings, in small clusters of 20 beetles or less
to hibernate. (Acorn, 2007) |
