Common Name: Transverse Lady Beetle
Coccinella transversoguttata richardsoni,
(R. Bercha, det.)
Length: 5.0 to 7.8 mm
Range: Throughout Alberta
Time of year seen: Summer
Other: Before the arrival
of the Seven-spot ladybug (late 1980's in Alberta), the Transverse Ladybug
was our most widespread and abundant ladybug. The arrival of the
Seven-spot caused a dramatic decline in Transverse ladybug populations.
Where once it was found in a wide variety of habitats, it is now found in a
limited number of habitats. These include pediment slopes in the
badlands, sparsely vegetated sand dunes and black spruce bog.
Occasionally, the odd specimen shows up in its prior habitats. (Acorn, 2007)
