Recently I was geeking out over the ladybug nymphs and pupae on my sunflower. Some of the neighbors came over to see what I was so excited about. Not all of my neighbors knew what ladybug nymphs and pupae look like and I thought it was important to show them lest they accidentally mistake them for pests and kill them!
On the left is a ladybug nymph. Some people think they're ugly little alligator-looking thingies but I think they're kinda cute! They're also very important in the garden, I can't remember the exact numbers but ladybug nymphs eat far more aphids than the adults!
On the upper right hand side of the top photo are two ladybug pupae. Obviously, they can't eat while they're pupating but it's still important not to harm them because soon they will emerge as adults and eat more aphids for us! And if we're very lucky they'll stick around to lay more eggs. This is actually the second generation of ladybugs on my sunflowers. Ain't nature grand? It's so grand that I didn't even plant this sunflower that I'm enjoying so much! I suspect that the birdies planted it for me, wasn't that nice of them?
Below is another photo of a different nymph, so you can see a little bit better what they look like.
As a general rule, when you see a pest in your garden you should wait two weeks before spraying anything, because even "organic" sprays can kill beneficial insects such as these ladybugs. If after two weeks you don't see any beneficials then spray if you must but with the least toxic spray possible. For many insects a good hard spray of water is enough.
I would also add that if you see an insect in your garden and you don't know what it is then don't automatically assume it's naughty and start spraying. It's very possible that your unidentified insect is nice, or even simply neutral. If it is naughty then it will attract nice insects, and while you're waiting your two weeks insects you can do research to find out what your insect is.
