Explanation of Names
Hippodamia convergens Guerin, 1842
Size
Length 4.2 to 7.3 mm (1)
Identification
full complement of 13 spots or only a few. The white lines that converge behind the head are common to all individuals.
Range
Throughout US and western Canada - Map (1)
in part to commercial sales for biological control.
Ranges to South America (Hoffmann and Frodsham 1993, White 1983). - University of Michigan Museum of Zoology
Habitat
may be abundant in agro-ecosystems (2)
Food
Aphids, also whiteflies and other soft bodied insects.

Remarks
Often found in numbers along lake shores, particularly in the spring and fall (3)
