7-spotted and Asian Multicolored Ladybugs

While transferring ladybug larvae to our fruit trees this morning I noticed something. There were two distinctly different kinds of larvae! Well, upon further investigation I found that we have (at least) two different kinds of ladybugs in the 'nursery'. One is the 7-spotted from western Europe and the other is called the Multicolored Asian Ladybug. Just yesterday one of the kids was looking at the 'nursery' plant and said, "Wow! That ladybug has a lot of spots!". Well, she was right.


So, the larvae I showed in the previous post belongs to the Multi-colored Asian Ladybug (Harmonia axyridis). The larvae I found today belongs to the 7-spotted ladybug (Coccinella septempunctata). These are not as spiky. They look more like little gray alligators with orange spots.


Here is the adult 7-spotted Ladybug.


The fruit trees are now full of ladybug adults, eggs, larvae and pupae. It's an amazing site to behold!

Here are some ladybug eggs on the underside of a cherry tree leaf.


Here is the in between stage from larvae to adult.


Watch out aphids! These kids are voracious!

Aphids and ladybugs - they remind me of the relationship between humans, tent caterpillars and paper wasps.

Here in Seattle, Public Works didn't succeed with caterpillar control until they allowed them to proliferate, thus providing enough egg laying media (the caterpillar head) for their natural predator, the paper wasp. I can't remember the last time I saw a rampant tent caterpillar infestation.

I don't even bother trying to control aphids anymore. If they get the best of a plant now and then, I know it's only part of a cycle that the ladybugs are usually on top of.

Looks like you had/have a nice little nursery going there!
