This past Saturday I went to Dedham Trail Day. There were tables from local businesses and organizations (free pulled pork and ice cream!) and a friendly atmosphere. But the main reason I went was because my friend [livejournal.com profile] dedhamoutdoors was going to lead a nature walk on a newly opened trail! photo IMG_6470_zps913e5d80.jpg
As I waited for the nature walk to start, I walked along the milkweed looking for creatures. I found several longlegged flies, but they move so quick that the only way to catch one was to get this shot of its shadow from below.

I'll be darned if I can remember where this is (a short ways from Rancho Palos Verdes) but by gum there was no passing by it without taking a picture. Thank god it was snapshot time too! Otherwise these would be a string of pictures of my brother my father and I in bars and in cars.

Whoops! I put Monday before Sunday on accident. Here I was at the strip mall swapping out my old sim card for a new one because we got new phones. Thus was ushered in the era of being able to receive phone calls in my kitchen.

Also, earlier that day we had an Urban Nature Walk in the Stony Brook Reservation. For whatever reason, probably excess blabbing on my part, this was the only picture I took.

Thanks to reader SB of Chestnut Hill Massachusetts for providing this photo of a crocus participating in an ecosystem in North America. This hairy little bee is just covered with crocus pollen. It's a lovely picture as well as a clear answer to my earlier query.

This should be especially informative for those of you outside the U.S.

In Utah women are primarily vessels for incubating children, and they will be punished if they act otherwise.

In Arizona, thinly veiled racism is alive and well. (bonus fun fact: Arizona was one of the last 3 states to make Martin Luther King day a holiday; the others being "Confederate Flag" South Dakota and our next state...)

New Hampshire is hilariously explicit with its bigotry!


I know you'll think I'm cherry picking weird news stories about politicians being insane, and I am, but fair is fair. My state?

In Massachusetts we equate voter frustration with flying an airplane into a building full of people.

There was a slight edge to the new vet's voice: "Who's good with spiders?" She's new, forgive her. I practically shoved my vet tech coworker aside to be the first to see the offending arachnid. (It's been a long fairly bugless winter, forgive me). A small gray spider, all 8 legs outstretched like the fingers on two hands, slowly descended on a silk line, just to the left of the new vet's desk. I didn't know she wasn't a spider fan. To her credit she merely wanted (with some urgency) for the spider to be relocated out of doors. Of course, no problem; but first: some pictures.

Weber's spider guide identified it as an "inconspicuous running crab spider." Ten syllables is a bit much for a common name, so I'll stick with simply "running crab spider," Genus Philodromus. The individual above is curled in a defensive posture, having had his fill of rough handling by the photographer. Normally this type of spider is flat against a wall, or (better for his camouflage) a tree. They spin no web, instead chasing down insect prey or seizing it caught unawares. They are not closely related to other crab spiders, like the goldenrod crab spider, or the giant crab spider.

According to Weber, a spider found in the winter is likely to be a youngster, which can even be found running across the surface of the snow. They mature in spring and produce eggs in summer. Weber implies that Adults don't survive a full year, but this one appears to be a mature male, by his size (5mm body length more or less) and his palps. Looking like little boxing gloves, the palps are sensory appendages that on the male are used in the delicate mating act. He uses them to convey a packet of sperm to the female's epigynum.* Suffice it to say: if your spider holds little boxing gloves in front of its face it's probably a male.

Why does the running crab spider come indoors? The short answer is probably "because it can." Its flattened body makes it more likely to see tiny cracks in doorways and windowsills as opportunities. Once inside the artificial tropics we provide, it has its pick of flies, moths and other household wildlife to prey on.



*I don't think I want to keep on describing spider sex, but this glossary was helpful to me, if you care to go on. It begins the definition of Epigynum: "The more or less complicated apparatus for storing the spermatozoa..." That's all I could take for now.

He's done it again! This time [livejournal.com profile] drhoz has posted a list of 10 sexually deviant practices found in nature. It's good science, it's funny, and it changes your idea of what "normal" is. There's every nasty and naughty variant you've thought of and others you haven't including SPOILER ALERT ) This pathetic mistake of evolution and nine others are yours to contemplate just by clicking this link.

For those of you who like to talk of such things (dirty sex things) you should know now that there is a word for having...untraditional sexual relations as a way to get around God's prohibition against premarital sex. Here it is.

On another note, I should probably retire my Musharraf icon, not to mention the one's referring to a certain other ex-president.

A judge has cleared a naked bicyclist of criminal charges because "naked cycling" in Portland is an "established tradition."  That helps me answer the question of what to wear while bicycling in all that rain...

As a semi-serious aside, Bobby Hammond was about the least coherent advocate for his cause that I could imagine, at least in his NPR interview.  Come on kid, you've had time to think about this!  Put together a lucid answer or two!

The groom sagely explained that his wedding was going to be half his relatives and in-laws, and half his drunken friends. Thus the underwear with the kilt. Even I'm jarred by seeing this on my journal, so I'm putting up an lj cut.

We walked the dogs around Leverett Pond today and it felt like an honest to goodness spring day. And thanks to my new hand-me-down camera, which Alexis used to take all the best 365 urban species photos, I was able to record some of it. Pictured above, I'm fairly certain, is a male palm warbler.

One of the best things about the new (8 months new) job is that I get to take (zoo)keeper training classes. This past week was an anatomy class, which, since it was only a single two hour session, was necessarily brief. Nonetheless, I learned some interesting stuff, and absorbed some cool facts, many of which are about sex:

Most male birds don't have penises. Only the 'primitive' orders do: the ratites (ostriches and emus and such), the cranes, the waterfowl, and the chickens (pheasants, turkeys, peacocks etc.) What was not discussed was why the penis was lost in more 'advanced' bird orders. I suspect it's all about minimizing weight for flight.

Most male reptiles are fitted with a pair of hemipenes, a forked appendage that mostly stays tucked in their cloaca (the single opening to the genital, urinary, and reproductive tracts). The hemipenes are not a penis in the sense we understand it: there is no internal channel; semen flows along grooves on the outside of the hemipenes. The hemipenes are simply a way for the male reptile to convey semen into the female's cloaca, rather than inject it.

Many male amphibians can be distinguished from females during the breeding season by the presence of nuptial pads, dark and rough patches of skin on the limbs which grasp the female during amplexus. Amplexus, for those who don't know, is what passes for mating in amphibians that lay eggs in the water (which is most of them). The male holds onto the female waiting for her to release her eggs in the water; when she does, he releases his semen. The nuptial pads provide much-needed traction, as anyone who has tried to hold onto a bullfrog can attest. The males only have these non-skid surfaces during breeding season. Sometimes people ask me the difference between a newt and a salamander. Newts are aquatic as adults, and the males develop nuptial pads for breeding. Males of other salamanders (it was explained to me) deposit a spermatophore, a packet of semen, and the female passes over it and draws it into her cloaca.

. . . .

Happy springtime to you!

Last Sunday there was an Urban Nature Walk in section of Franklin Park called "the Wilderness." It's a wooded puddingstone hill, originally intended as a place where city dwellers could experience what it looked like in the area before European Settlement. Here Pete has climbed a puddingstone ledge.
