Yelena told me I needed to buy ladybugs because they keep the milkweed clean from aphids and won't disturb the eggs or caterpillars. But... I found a big one already on there! Nature is taking care of itself.
Funny was that in the Pre-K class I subbed last week we talked about ladybugs (US) and ladybirds (UK). There was a kid from the UK and it got confusing they got confused ;).
