The Catalpa trees grow and the big heart-shaped leaves attract aphids, lots of aphids. The aphids, tiny little white sucking machines, coat the leaves with their “dew” — what goes in must come out in some form — which in turn attracts ants and wasps. The aphids themselves attract ladybugs, hungry little beasts. All the dark things on the leaf above are early-stage instars of lady beetle larvae, which look absolutely nothing like the shiny, round adults. This photo and the one below are shot with my camera’s macro through a 10x loupe. The ‘gator-like larval stage ladybug — see the two spots on its side, like the adult Two-spotted — is surrounded by aphids; these aphids are so small they can barely be seen with the naked eye. I don’t know if these are instals of A. bipunctata, but suspect so. I doubt that’s my hair, since I was wearing a hat. This one is so plump I suspect it’s close to pupating.
I have read that some localities ban Catalpas because they are messy trees, dropping foot-long, dried bean-pod-like seed pods, dripping with sticky goo, swarming with insects. But let’s hear it for mess! Nature is messy, complicated, interrelated. It is not a lawn or vast monocultural farm field soaked in poisons, which, as we keep learning over and over again, do tend to move from the insects and plants they are aimed against to fish and reptiles and birds and mammals, including the very people who apply the toxins and the rest of us. Quelle surprise! Luckily, Brooklyn Bridge Park has had the vision to plant Catalpas all over the place. And almost every one of these trees has Two-spotted ladybugs in them. Remember, this is a species that isn’t being seen as much as it used to be. Above and below, Two-spotted pairs are engaged in making more of their kind.Remember, too, that while the standard Adalia bipunctata is red-orange with two black spots, there are melanistic variations that are black with four red spots (or squares as in the side markings here), among other patterns.Here’s what the loupe/camera set up view looks like before cropping. Rest of my left-hand fingers are supporting the leaf from underneath. I’m amazed these came out this well. I wrote most of this post some weeks again, but a cursory look yesterday found three adult TSLs underneath some awfully bedraggled looking Catalpa leaves. Three cheers for bedraggled!
For my first discovery of these rare beetles two years ago on these trees, see here.

The trees are alive with the sound of music. At night. Katydids and crickets stridulating away, rubbing the pegged “file” of one wing against the ridge-like scraper of the other to produce those clicks, tisps, buzzes, etc. Each species has a distinctive sound: it’s the males marking their territory and calling to the females. Bonus fact: The ears of katydids and crickets are usually located on the foreleg tibia.
You know where our ears are. We’ll hear a great chorus of arthropod fiddlers in Prospect Park tonight on our Night Listening Tour. I haven’t run across many katydids in the light of day, but here’s one, two, and three other examples.
The specimen picture above was spotted on a milkweed leaf. I thought at first it was a grasshopper. Grasshoppers, crickets, and katydids are all members of same family, Orthoptera, so there are similarities. What makes this a katydid, however, are the very long antennae and the very long ovipositor (out of focus). I think this one is in the genus Orchelimum, the great meadow katydids, a.k.a. gladiator katydids.

Last night as I watched the sun tuck behind the embankment of New Jersey, a fisherman beside me on the end of Pier 5 reeled this fish out of the dark water. He thought it was a Sea Robin, but I didn’t. It wasn’t that weird. Some research reveals it to be an Oyster Toadfish (Opsanus tau), a species with a high tolerance for hanging out in the bottom murk of polluted, junk-filled waters. Also known as oyster-cracker, ugly fish, mother-in-law fish, etc. It doesn’t have scales, but rather a slimy skin, hence the allusion to toads. The strong jaws are good for cracking oysters and other shellfish, but they will eat anything they can get. They are also known as a vocal species: males make “foghorn” like noises to attract females.
The bright yellow is the lure. Having maimed the 8″ long creature for sport, the fisherman extracted the hook and threw it back in.

A male Common Green Darner (Anax junius), one of our largest species of dragonfly. You should really click on the picture for a larger view, since there is some great detail here because this one perched quite a while below eye-level, allowing us all good looks as he rubbed his front legs over his eyes. Note how large those eyes are: dragonflies are like raptors, depending on vision to hunt. A migratory species, this three-inch long darner is usually the first dragonfly seen in the spring and one of the last in the fall (a female is pictured in the link).

Painted Lady (Vanessa cardui). I’ve posted previously about separating these from the similar American Lady butterflies (Vanessa virginiensis); from this view, the four big wing spots mark the Painted; two big spots the American.Orange Bluet (Enallagma signatum) male. Small and slender, but striking when you see it: at Green-Wood’s Sylvan Water. At the nearby Valley Water, the Orange Bluets were mating. Common Green Darners (Anax junius) were also reproducing there. Here the male continues to hold the female as she deposits eggs. I have seen females of the species depositing eggs on her own, sans the grip.Northern Cloudywing (Thorybes pylades). I wish there was a special place in hell for the people who just toss their butts any- and everywhere (take a look down street gratings some day). This Familiar Bluet (Enallagama civile) male seems to be less censorious. A couple of Cerceris genus wasps were hanging out on some rogue squash plants on the edge of the Long Meadow.Common Sootywing (Pholisora catullus) hitting the light just right on pollinator-magnet Buttonbush (Cephalanthus occidentalis).
