Daddy-, or Granddaddy-longlegs… but wait a minute. There are only six legs here. The Opiliones order of harvestman are related to spiders and have eight legs. What’s going on? It looks like the first joint to the right of the face is missing a limb, so presumably is the other side. Missing that joint, too, it looks like. This one could still move pretty well, though. There are over 5000 species of these critters in the world, with 235 known in North America (these numbers from Evans, who pictures two of them; so many bugs, so little time!). They aren’t venomous, and don’t have fangs so they don’t bite. The dark nob on top is an eye. As I was getting the lens close, I felt another on my camera hand, smaller bodied and lighter colored. I blew gently on it to get it to reverse course.

Walking Stick on Peter’s bins. Texas has at least 16 species. Leaf-cutter ant (Atta texana) highway. The ants are returning to their sprawling underground colonies with leaf fragments, which, farmer-like, they feed to the fungus they actually eat.Thornbush Dasher (Micrathyria hagenii).Band-winged Dragonlet (Erythrodiplax umbrata).Antlion. This is the adult stage.We saw many antlion traps, where buried nymphs wait for their lunch to fall down into the soft sand pits. Large Carpenter bee of some kind in the bottlebrush. Texan Crescents (Anthanassa texana) perpetuating the species.
I think this is a male Arizona Desert Tarantula (Aphonopelma chalcodes), also known as Arizona Blond Tarantula because of the female’s coloring. Our intrepid, and hawk-eyed, guide Jake swerved the van out of the way and then backed up to coax this spider onto his hand. And then, up his wrist.The males wander over a wide range searching for females this time of year, usually at night. The reddish hairs on the abdomen are urticating, that is stinging, so no petting. The bite is no worse than a bee sting. But according to the American Tarantula Society (well, obviously!) the things are harmless. I hadn’t read that when Jake offered up a chance a to hold this guy. There were various “no thank yous,” from my van mates but I proffered my hand… cautiously, but eagerly.
I was breaking down a head of broccoli and had gotten to the best part, the stem, which unfortunately was hollowed out by rot, when this one scootled across the chopping block for the cover of cleaver on its side. What the hell, I thought, good luck, spider. Later, though, it started up the wall and looked out of place so I captured it and released it into the Back 40.
Back to the great Southwest tomorrow.

Fiddler crabs in the tiny patch of ever-so-green right now salt marsh at Pier One. On the jumbly rocks next to it, a number of these spiders:I have returned from a two week trip abroad. I have a new computer. I am ready to blog again.A young New World Robin, SO different from the Old World ones, as pictured yesterday.

Last week, on the first day of spring, a spider found itself in the tub.An American House Spider (I think), Parasteatoda tepidariorum. I got close with the camera and somehow brushed a line of silk, so that when I moved away, I inadvertently pulled the spider with me: it danced like a tiny puppet at the end of that invisible line. Sorry! And then I noticed, that being in a tub, which is designed to shed water, it was having some difficulty in getting out. So I used a small scallop shell, typical bathroom equipment in this house, to gently move it. As some of the guides noted, it played dead for a while but was soon on its way. Wherever it wanted to go.
Last month, I watched a spider feed heartily and then build a silken sac for her young. Two weeks ago, the young spiderlings emerged from the sac. And just sat there for several days. Then the mother spider disappeared. And a few days after that, all the little ones. In the outdoors, some young spiders disperse by ballooning, releasing threads of silk that catch the breeze. In our House of Spiders, they may to a little of this as well as motivate with their eight legs.
And in this corner, a click beetle, so named because they make a “click” when they flip up into the air (it helps them turn over should they find themselves belly-up) and a spider. The battle, such as it was, lasted for most of a day. I could hear the haunting click from a neighboring room. Then the spider, having won, started drinking, and that lasted for most of a day, too. And then some two days later:This egg case was clearly fueled by all that click beetle juice. I assume that’s the male on the left, typically smaller when it comes to spiders.
I have to say, spiders are not to be emulated as good housekeepers. Once they’ve drained their prey, they have a husk of an exoskeleton remaining (try some shrimp shell). So they discard it, in this case into corners, window sills, etc.

Two summers ago, a Black and Yellow Mud Dauber wasp built her nest in the Back 40 (inches). A new generation of these large, black-bodied wasps with yellow legs emerged in June of last year. This year I had one inside the house. Not here in Brooklyn, but at the family house in Massachusetts. This wasp was building her nest in the front door frame, between the screen and house doors. The screen door of the old manse is sagging, so there’s a gap at the top, which allowed her access.As the name mud-dauber suggests, these wasps build their nests out of mud, individual cells first, then a surrounding stucco of mud around the cluster of cells. Here she was just starting out. One of the inch-long cells had been sealed, the other was still open and unfilled.Inside each cell, the wasp lays an egg atop the provisions she has brought for the larva-to-come. The young eat paralyzed spiders.I shooed the wasp out of the house half a dozen times before I found the location of the developing nest. Regretfully, I broke it up and found these four spiders in the sealed cell. But then a couple of days later, in the same door frame, clearly an excellent location — water is dried mud’s worst enemy — another cell appeared. It’s darker on the left hand side of the cell because the mud there is still wet.This one had thirteen spiders crammed into it.There are several different species of orb-weavers here. The abdomen certainly do look meaty.Really sorry I had to break up the housekeeping here, considering the huge amount of work this one wasp had to do. She carried bit after bit of mud — it’s been dry on the island too, but I’m guessing the construction site next door might have been a source — and hunted down the spiders on her own. Like a lot of adult predatory wasps, she herself is a vegetarian, supping on nectar. Meanwhile, there are cleptoparasitic wasps who like to avail themselves of the provisioning the Black and Yellow wasp does. Endlessly fascinating is the natural world.
