Bugs without Bios V
The BugLady dedicates Bugs without Bios episodes to insects about whom, despite all the words that are floating around out there, she can discover only a little information.

In lieu of the usual bug biography, the BugLady presents The Twelve Bugs of Christmas—a tribute to a dozen insects (a Baker’s Dozen, really) that were photographed this year but not featured in a BOTW. Let the singing commence.
Orb Weaver Spiders have been practicing their craft for some 140 million years. With more than 10,000 kinds of Araneids worldwide, they account for about a quarter of spider species. OWs will often tackle prey that is larger than they are if it gets snagged in their web. They first paralyze it with a toxic bite, then wrap it, and later eat it.
The BugLady has many pictures of bugs about whom she can’t find enough information to write a complete biography. Here are three more of them.
Six-Spotted Fishing Spiders are found in wetlands, especially wetlands bordered by lots of vegetation, and they’ve developed multiple ways to get around within their habitats. There are 100-plus members of the genus worldwide, nine of those species in North America—four live in still water; four in streams, and one is found in trees. SSFS can dive underwater, and can easily take a tiny fish and can stay submerged for more than thirty minutes.
The BugLady takes lots of pictures as she moseys around—flowers, landscapes, a surprising number of people, and, of course, all manner of bugs. Bug pictures may stall in the BugLady’s X–Files, awaiting identification—some for a long time. Here is a selection from the X–Files. In some cases the BugLady knows part of the story; in others, even less.
The BugLady has always enjoyed mullein plants (Verbascum thapsus). Oh, she knows that they’re sun-slurping aliens whose mission is to blanket the earth at the expense of native vegetation, but they produce cheery yellow flowers, and they stick out of grassy fields like skinny saguaro cacti.
The BugLady has been stalking invertebrates that hang out on the east wall of the Field Station lab. The wall is painted cinderblock that warms up in the morning and probably keeps some heat as it gets shaded in the afternoon. Grass grows right up to the edge of the building. The BugLady hypothesizes that bugs can enjoy the residual warmth without getting fried by the sun, because she sees some small critters on the north wall but very few on the bright south wall. She found some familiar faces and some new ones—plant-eaters and an array of carnivores that come to collect the herbivores.
When the weather conditions are right, warm enough for thermal updrafts but not too windy, young spiders and even adult spiders of the smaller species climb to the top of a tall object, face into the wind, and release one or more fine strands called gossamer. Thermal updrafts pick up the line—and the spider—for a trip that may span inches or hundreds of miles.
It’s a good thing that the BugLady doesn’t have nearby neighbors (or a Home Owners’ Association) who might be alarmed about someone who turns on the porch light and then creeps around taking pictures of porch critters at midnight.
