More Adalia bipunctata

 

This spring, I’ve spotted Two-spotted Ladybugs all over the place in Brooklyn. Down the street. In nearby Green-Wood Cemetery. In Greenpoint. And most recently inside my apartment!

The beetle was on the inside of a window. I captured it by maneuvering a stiff postcard under it — that is, getting it to walk onto the postcard instead of the window — and capping it with my loupe. However, being shy and retiring, it refused to be photographed, so I released it out an open window.

Just a few years ago, Two-spotteds were pretty rare in New York state, after having once been common here. What’s going on? Any chance they’re being released?

Raptor Wednesday fans: I’m barely seeing any raptors right now. Breeding season and all. Last sighting was a Kestrel on Monday. 6:15 a.m., heard first out the window, seen jetting and stooping over Sunset Park. This was a full ten days since the last, a Peregrine on 6/9. Still doing better than one a day, though: 295 raptor sightings this year.

Ladybugs

The first four photographs were all from on the same patch of milkweed (Ascelpias syriaca), not yet in bloom but already festooned with aphids.Multicolored Asian, Harmonia axyridis. There were several.
Checkerspot, Propylea quatuordecimpunctata. The only one noticed.
Two-spotted, Adalia bipunctata. Counted four. Getting busy and laying eggs. This is one of two egg clusters on the underside of different leaves of the same plant.I also found some Two-Spotted in Greenpoint. There were more Multicolored Asian LBs as well there. Then I hit the MALB jackpot at Bush Terminal Park, where there were quite a few on an expanding patch of mugwort (there’s an epic battled between mugwort and cottonwood there). There was at least one Seven-spotted (Coccinella septempunctata) at BTP as well.

Bipunctata in Sunset Park

Two-spotted Ladybug (Adalia bipunctata). Back in 2012, I reported to the Lost Ladybug Project that I found some of these critters in catalpa trees in Brooklyn Bridge Park. From the LLP, I learned that mine was the third New York State record for this species, and the only one in NYC. There was much rejoicing.Yesterday, I found them down the street, in some street tree swamp white oaks (Q. bicolor) on 5th Avenue here in Sunset Park. These trees are still young enough that I can reach into their leaves and branches. The invasive Harmonia axyridis like these same trees.

There is some color variation in the Adalias, as you can see (and the black ones have four spots…). Like many a living insect, these lady beetles are hard to photograph. They also seem to have a loose grip on the leaves; they’ll often fall off if I touch the leaf intending to turn it toward the camera, but luckily they can fly. Not so the larval stage of the species; these gator-like forms have a good grip and steady jaws.

Atalantycha bilineata

Two-lined Leather-wing, also known as Two-lined Cantharid. One of the soldier beetles. This is one of the earliest Cantharids to emerge in the spring, evidently. Found from Nova Scotia on down. This one spotted in Virginia three weeks ago, where/when not too much else was flying.

According to Wikipedia, soldier beetles (Cantharidae) were called such because one of the first described had the colors of a British Redcoat.

Tiger Beetle

Cicindela limbalisA Common Claybank Tiger Beetle (Cicindela limbalis). Also known as the Green-margined Tiger Beetle. Spotted by a owl-eyed friend on a lichen-anchored rock on Mt. Taurus up above Cold Spring, NY, on a recent hike. Tiger beetles, in addition to being stripy are fast-moving predators of other insects.

Shelter From The Rain

Should I submit this to bugguide.net to see who can identify it from this angle? Or would that be cruel? Actually, we have a good look at the here, if not the patterning of the topside. I think it could probably be narrowed down a bit. Tiger beetle?

More Beetlemania

Sehirus cinctusThis tiny beetle is Sehirus cinctus, the White-margined Burrowing Beetle. 4-6.5mm long. There were several on the very hairy leaves of what looks like Stachys something or other.

Adult females of this species care for their young, which is fairly unusual in the insect world. Plenty of insects provision their young, but most aren’t around to feed them directly. Wasp mothers, for instance, who feed their young with paralyzed spiders die before they see their next generation. But let’s not get sentimental. Different strategies for different folks.

These beetles can sometimes swarm on your ornamentals, but they are harmless feeders on the seeds of mint family plants, so leave them alone. And for the planet’s sake, don’t spread the poisons of pesticides/insecticides: that shit harms beneficial insects and ends up in the water and, surprise, surprise, you, too. Sehirus cinctus
