Multicolored Asian lady beetle (Harmonia axyridis)

20 March

Time for an insect.

This Asian beetle was originally released in the US to help control pests, and has established itself very extensively. So extensively in fact that it has very much replaced the naticve species in Canada – this example was just one of the many, many that come indoors to see the winter out and then start to emerge about now as light levels increase. Some days we catch dozens of them and have to evict them.

They, adult/larvae, eat many species of soft-bodied insects, including aphids, scales and psyllids. The adults come in many shades of red and orange. The number of spots can very greatly – sometimes they have no spots. They are identified by the “m” or “w” on the backs of their heads. Idf we come across any actual native labdybirds (or ladybugs as some call them) between now and the 1000 target be assured that they will be shred with our followers.
