The BugLady would like to dedicate this episode to the late (great) Cornell Professor Richard B. Fischer (January 19, 1919 – August 7, 2005) who taught the BugLady how to sneak up on insects (no bobbing or weaving, just slow and steady and straight ahead.
The Spotted Nomad Bee belongs to an overlapping continuum of species named the Nomada ruficornis species group. The Nomada (nomad/roaming bees), one of the largest genera in the Nomadinae subfamily, are a confusing bunch taxonomically. There are about 300 species in North America and 700 species worldwide.
As a group, Bumblebees are northern bees, tough enough to survive north of the Arctic Circle. They can thermoregulate;—producing heat by “shivering” their flight muscles without beating their wings, and retaining it via their thick, insulating hairs. They need an internal temperature of 86 degrees before they can fly.
The BugLady has been out with her camera, walking non-aerobically and peering into plants. The “peering” has resulted in some interesting (if blurred) sightings (her macro lens is getting a bit cranky). Amazing things have been happening on milkweed, probably spurred by a banner crop of aphids on the leaves.
Sphecodes bees are parasitic solitary bees in the large, but mostly-not-parasitic. Sphecodes bees are sometimes called cuckoo bees. Cuckoo bees are kleptoparasites (which may also be spelled with a “c”). Like their avian namesakes, they deposit their eggs in someone else’s nest—in the case of CBs, in the nests of fellow-Halictids.
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.
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.
People get excited when pussy willows whisper the spring. The BugLady thinks it’s more fun to skulk among the pussy willows when they are actually blooming (the gray, fuzzy “bud” is the future female catkin), ogling the diversity of insects that come to visit. Willows are dioecious (separate house), bearing their male and female flowers on different plants
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.
“True” Bees have, somewhere on their body (particularly on the thorax), hairs that are branched or feathery, not simple, and the top of the first segment of their thorax looks kind of like a collar. Bees are pollen-eaters, so most species also have some mechanism for collecting it. Honey bees and bumble bees are easily recognized, but distinguishing between the different tribes and families of bees can be sticky.
