Ladybirds are go

Australia has plenty of native ladybirds, but this amorous pair belong to the European white-collared or spotted amber ladybird (Hippodamia variegata). First recorded in Australia in Gatton (SE Queensland) in 2000, the species is now widespread and is used in biological control of aphids and psyllids.

Although the background colour and the number and shape of the markings are variable, the white-collared ladybird is distinguished from native species by the white yoke on the pronotum (the 'shield' between the head and the wingcases).

Either I don't see them or we don't get many ladybirds in my garden.

I also don't have much in the way of aphids either. Guess the ladybirds are off in gardens raging with aphids.

I didn't know there was varieties of them. I know of the "evil" ladybird.
