Brooklyn’s Two-Spotted Continue

Two years ago, I stumbled upon some unfamiliar ladybugs. There were Two-spotted (Adalia bipunctata), which turned out to be rather rare. It was the first Brooklyn report for the species. Last summer, the site was inaccessible to civilians because of construction. This weekend I took a look at the trees, as I usually do. They have been quite active with Multicolored Asian Ladybugs (Harmonia axyridis) for the last couple of weeks. But hello! Something different from the very round, very large (for a ladybug) H. axyridis, a nuisance species, if not worse, spread by gardeners and garden-suppliers. Indeed, many think the spread of these beetles has been the cause, or one of the causes, of the decline of the likes of A. bipunctata and other now rare native species.

From the Lost Lady Project, I’ve learned that A. bipunctata has been reported at four New York State sites. Like many native species, it has been declining in numbers for the last twenty years or more. The location here is tiny, just a few trees, and isolated from other bits of green. It shows the importance of having a variety of trees and plants in as many places as possible. But this location is much busier with humans than it used to be…

Only three other places in New York! This isn’t to say there aren’t more places, which haven’t been discovered because there aren’t as many people looking for lady beetles as, say, there are people enabling FIFA’s looting, and/or staring at their toenails, but it does suggest their specialness.

    wow! I had no idea. These beetles are really beautiful, the phone pic being no exception. I have not seen any of these, but maybe was not paying enough attention. I really enjoy your blog as you are more a naturalist that attached to any one thing. Well, you do love birds, but not exclusively. Thanks.
