“A toast to the glorious life (and messy death) of Brood X cicadas,” by Bonnie Berkowitz.
The cry of the cicada
Gives us no sign
That presently it will die.

Brood X has peaked, the little red-eyed guys have done what they set out to do, and they are passing away.
“When animals die they have a pretty distinct BAD smell,” wrote Paula Shrewsbury, also a professor of entomology at the University of Maryland, in an email. “As part of the decay process there are a number of interactions between enzymes and microbes that result in the ‘smell of death.’ Cicadas are no different than other animals; when they die they smell bad.”

Three nice Brood X pieces, from Nell Greenfieldboyce, Bonnie Berkowitz, and John Kelly.
Of course Ed Yong found a different angle on the arrival of Brood X: “Cicadas Have an Existential Problem.” And a clever analogy to illustrate what’s going on.
Home football game, nice weather, and the last weekend before school starts, so the listening wasn’t that great for Team Reston for this year’s Cricket Crawl.
Heard during my 1-minute sample: Common True Katydid (Pterophylla camellifolia) and Lesser Anglewing (Microcentrum retinerve).
Kevin Munroe, with assistance from P.J. Dunn, has launched a new online project, cataloging the 65 dragonfly/damselfly species to be found in Northern Virginia. ID guides, tips on where to look, flight time calendars, field guide recommendations, and more!
A roundup of conservation and natural history links:
Several families were found in more than 90 percent of homes: gall midges (Cecidomyiidae), ants (Formicidae) and carpet beetles (Dermestidae), along with cobweb spiders (Theridiidae), dark-winged fungus gnats (Sciaridae), cellar spiders (Pholcidae), scuttle flies (Phoridae) and book lice (Liposcelididae). Most houses also had dust mites (Pyroglyphidae).

When clashes occur, it is all too easy to fall back on reductive notions about liberal, elite environmentalists and conservative, redneck hunters—the “greens” versus “the hook-and-bullet crowd.” With partisans on both sides invoking stereotypes and the media portraying hunters and environmentalists as opponents, it is tempting to imagine stark lines between the two.
But such divisions are too simplistic.
As natural history has been de-emphasized, molecular biology, genetics, experimental biology and ecological modelling have flourished. But here is the problem: many of those fields ultimately rely on data and specimens from natural history….
No biology student should get a diploma without at least a single course in identifying organisms and learning basic techniques for observing and recording data about them.

A likely upside to this winter’s unpleasant cold snaps: Thomas Kuhar of Virginia Tech reports that 95% of Brown Marmorated Stink Bugs (Halyomorpha halys) have been unable to survive the icy temperatures. Kevin Ambrose has the report.
Brood II of the 17-year cicada is expected to emerge in Virginia this spring.
From last summer, Joe Palca’s two-parter (one, two) about Scott O’Neill’s 20-year efforts to find a biological means to control and eventually eliminate dengue fever. I like the focus of Palca’s series: it’s not just about the newest published scientific results, it’s about the process of doing science.
“You know, I was incredibly persistent in not wanting to give this idea up,” O’Neill said. “I thought the idea was a good idea, and I don’t think you get too many ideas in your life, actually. At least I don’t. I’m not smart enough. So I thought this idea was a really good idea.”

Making connections: a roundup of nature stories that have caught my eye recently:
Via Via Negativa, a new botanical-entomological citizen science project pops up from U. C. Davis and the U. of Toronto: monitoring of pollinators of Spring Beauty (Claytonia virginica and C. caroliniana).
Via The Economist, recent research published by Evan Preisser and Joseph Elkinton yields an interesting result to those concerned with the conservation of Eastern Hemlock (Tsuga canadensis) trees. From Virginia to Connecticut, the species has been getting clobbered by an invasive hemipteran, Hemlock Woolly Adelgid (Adelges tsugae), native to Asia. However, comes another sap-sucker, Elongate Hemlock Scale (Fiorinia externa), also invasive, to feed on the hemlock. According to the paper, in experimental infestations, trees inoculated with both bug species fare better than those inoculated with just the adelgid.
