Backyard and Beyond

Starting out from Brooklyn, an amateur naturalist explores our world.

As John Burroughs said, “The place to observe nature is where you are.”

  • 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…

  • Oak Galls

    The mighty oaks and their galls are an endless source of curiosity. This particular type, a hard, fruit-like structure, is created by a tiny wasp, which essentially irritated the tree into making them for their larva. Clever boots! The trees are Swamp White Oak (Q. bicolor), according to the Street Tree Map. (I’m waiting on…

  • Thoreau Thursday

    The other day, when I noticed a host of gnat-like flies outside the kitchen window, it was 54 degrees F and overcast. Nothing to see here, people, move along. Well, actually, we can see an awful lot here. The top specimen is, I assume, male, because of those moth-like feathery antennae; the better to sense you with,…

  • Wooly Bear

    Our old friend the Banded Wooly Bear caterpillar, bearishly larval stage of the Isabella Tiger Moth, Pyrrharctia isabella. This was found behind a large piece of bark, which was put back. Have you heard the one about judging winter’s length/severity by the amount of black and/or orange on the animal? Turns out that the colors…

  • Cocoon

    The winter woods are quiet and relatively monotone in color. But look closer. (And listen!) We were looking at tree buds. This big cocoon with remnants of leaf-covering was just hanging there. One of the giant moths of the family Saturniidae made this, I think. Will it make it? Has it already be taken over…

  • Oak Wilt

    Damn it! I really wanted to start on a positive note, but the bad news just keeps coming. Oak wilt has been discovered in Brooklyn. This is a lethal fungal infection of oaks and other species, its spores spread by beetles. When I was in Green-Wood on Friday, I heard a chipper hard at work.…

  • Spiny Gall

    Witch-hazel (Hamamelis virginiana) is a good gall-tree. One species of aphid, Hormaphis hamamelidis, forces the tree to make cone-shaped galls on the leaves. The young aphid grows up inside this, protected from its enemies. Another species of aphid, the Spiny Witch Hazel Gall maker, Hamamelistes spinosus, makes the tree make these hard, spiny galls that…

  • Variegated

    A Variegated Fritillary (Euptoieta claudia) yesterday in the Buddleia pollinator-magnet at Green-Wood. First time I’ve seen this species here in NYC, although I’d seen one before in Arizona. They’re a southern species, uncommon here, but have been known to get up to Canada.

  • Tiger Beetle

    A 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. This was the view from up there.
