I didn’t know, till yesterday, that ladybugs actually develop from larvae. Never even occurred to me, but it was because I noticed some on our powdery mildew zucchini leaves and saw they were the same colour as the ladybugs that I thought I’d do some research on this.
There were lots of ladybugs and several larvae on our mildew covered zucchini leaves. I’ve since been informed by a gardening friend that the yellow & black ladybird is definitely a goodie, they are attracted to powdery mildew on zucchini and the like because they feed on it and it’s only the yellow & black ones that do eat it. So we’re glad to see them in our garden!
