Nine-Spotted Lady Beetles

Do you remember when the Flatbush Gardener released Nine-spotted Lady Beetle larvae in his native meadow garden? Coccinella novemnotata is the New York State insect, but it is almost non-existent now in the state. In fact, the species is hardly to be found anywhere in the east. Cornell’s Lost Ladybug Project has been working to both document and re-introduce the species, which may be endangered by all the god-damned invasive lady beetles introduced by people thinking they’re doing a good thing.Anyway, no sign of that original release in 2016 were ever seen again. This week, FG tried again, this time with both adults and larvae. (Same plump larva under flash above and natural lighting, below.)
How will they fare? Some neighbors are receiving them too, to spread the wealth up and down the block. This is a unique part of Brooklyn, with substantial houses on suburban-style lots. It’s good and tree-y, but has an awful lot of lawn, which is habitat for very little. Flatbush’s all-native species yard, front and back, really stands out, but there is some creeping diffusion of his model nearby.
There were very robust specimens, packed with aphids. In both senses: the containers — available here — come with food for the little beetles, and they evidently eagerly partake of said food. Yum, aphids!It was very drizzly-misty that evening, rather more than a mizzle at some points. The adult beetles quickly tucked themselves out of the way under leaves.
Good luck, little ones!

Various Insects

Polished Lady Beetle. The gloss on these things! You can see the trees overhead reflected in the elytra*.Red-banded Leafhopper. You must get close to this little one to see this wild pattern.Invasive European Wool Carder Bee. They hover very much like flies and are quite territorial. All over now, they were first detected in New York in 1963.Oleander Aphids.So many wasps, so little time!A Least Skipper, first one I’ve seen. In the marsh area of Pier 1, Brooklyn Bridge Park. *Beetle forewings have evolved into hardened coverings for their hindwings. These coverings are called elytra. Elytron is the singular. On this firefly they are opening in preparation for flight……beetles are not the greatest fliers in the insect world.

Speaking of flying: hot off the scientific press is news that captive-raised Monarch Butterflies don’t know how to migrate. Here’s another abstract.

Isn’t Monarch-raising rampant in schools? Who will tell the teachers? What about other butterflies and moths? Hobbyists are mentioned, too, since in-door raising of wild-caught Monarchs also results in the loss of the ability to orient south. But not all butterflies and moths are migratory… yet the study found that commercial Monarchs have differently shaped forewings than wild ones.

To market, to market; it is devouring the world.

I looked up the National Association of Biology Teachers… and noticed that one of its funders is Monsanto. The Octopus surrounds us.

Insects Update

A couple of American Snouts. Um, yes, that’s their rather descriptive common name. Libytheana carinenta is a lot more common south and west — I’ve seen them before in Texas. Their larval food plant is hackberry. There were three mature hackberries above this understory. What an illustration of the relationship between plant and animal! I first thought this tiny beetle was a lady bug of some kind. But some searching of the usual suspects came up with nothing similar. I started to look closer: those antenna are too long for a lady beetle. With some help from a couple people on iNaturalist, we narrowed this down to Scirtes orbiculatus, one of the marsh beetle (a family I wasn’t even aware of). It doesn’t seem to have a common name. There were at least two on common milkweed.Speaking of milkweed, I caught a glimpse of my first Monarch caterpillar of the year in the same patch. As I was trying to focus:A European Paper Wasp flew in and took the caterpillar down. Yikes! That’s a lot of meat… and so much for milkweed’s toxic latex protection. These wasps will eat the adult butterflies, too. Speaking of eating, this aphid better watch out. Asian Lady Beetle larva in proximity…! Eastern Amberwing dragonflies are out and about. Fairly common, our smallest dragonfly.

More Insects

The Common Sootywing. The Kaufman guide says “flight is slow and close to the ground” but I beg to differ with the first characterization. This was about the tenth I’ve seen in various places before I could get a photo.Black Swallowtail, another mover, if not shaker.This is a Great Blue Skimmer, another case where the description of the adult male gives us the common name. This is the female. This photo makes her look smaller than in real life. The larval Asian Ladybug (they seem to have dropped the “multicolored” in the common name; what’s distinguishing about them is that they are variably spotted in the adult form).

No photo, but on 6/2 I spotted a Two-spotted Ladybug in the same Brooklyn Bridge Park patch I first found them in in 2012. I also wrote about them for Humans & Nature.

Ladybugs

Two Spotted Ladybug, Adalia bipunctata.Wait, there are four spots, or two tiny dots and some squarish sides? This is one of the melanistic forms of the species. First one I’ve seen this year, on a tree in between Third and Forth Avenues.

Others seen since. It’s definitely insect season.

Insects

Harmonia axyridis, the Multi-colored Asian Lady Beetle, is known in the UK as the Harlequin Lady Beetle. “Harlequin” is a better common name than MALB, which is a mouthful and has a whiff of racial baggage to it, particularly when added to invasive. This one was one of two spotted in Denmark, the only lady bugs seen on this trip. The Swedes, meanwhile, really seem to like their spiders. There were many webbing the inn we stayed in. There were more than a few indoors. All fine with me. And here’s a neighbor in the Bronx, on a window-spanning web right in front of a fan blowing out. Has been hanging out for more than a month now. One of the biggest orb weavers I’ve ever seen, a good 2″ from toe to toe. Yellow-collared Scape Moth (Cisseps fulvicollis) back in Brooklyn. First time I’ve noticed the red tongue.

Milkweed Madness

A field of Common Milkweed, Asclepias syriaca, home to just above everybody.Silver-spotted Skipper (Epargyreus clarus).Fourteen-spotted Ladybeetle larva, Propylea quatuordecimpunctata.Large Milkweed Bug, Oncopeltus fasciatus.Above and below are two variations on larval stage Harmonia axyridis, the Multicolored Asian Lady Beetle.Don’t forget all the flies and bees. Also, Yellow-collared Scape Moths.Anthrenus genus carpet beetle, I think. Tiny.And Oleander aphids (Aphis nerii).
