First cicada killer sighting of 2010

July 19, 2010

Cicada killer wasps appeared as early as July 7, in our yard.  This year we had a cold winter, with snows that appear to have stymied even the nasty, invasive Argentine fire ant.  But June was dry and hot.  July came with rains, and cicada killers don’t like wet soil to dig in.

For that matter, we don’t have many cicadas, either.

Plus, we had to tear down a planter box attached to the dining room window, since it hid termites too well.  No doubt that planter had young from the cicada killers in it.

Early yesterday evening, as we finished dinner, we watched the house finches (Carpodacus mexicanus) escorting their young to the bird feeders, the cardinal “babies” (Cardinalis cardinalis) breaking out of their baby feathering, we looked for the family of red-bellied woodpeckers (Melanerpes carolinus) — and there it was:  One lone cicada hawk zooming across the patio, yellow-and-black striped abdomen standing out among the other paper wasps (almost certainly Sphecius speciosa).

They’re back!

Rasberry Crazy Ants – where’s Godzilla when you need him?

September 12, 2009

Texas holds more than its share of nasty pests:  Imported Argentine Fire Ants, Canadian thistle, zebra mussels, creationists — and now, Rasberry Crazy Ants, Paratrechina sp. nr. pubens.

(Hey, Texas A&M spells it “Rasberry” without a “p,” so do I.  It’s named after Pearland, Texas, exterminator Tom Rasberry, who first identified the Texas pest.)

Remember the wonderful old Japanese monster movies, where monsters from past Tokyo ransackings would return to fight the new monsters?  Texas could use a good Godzilla or two.

Texas A&M’s Center for Urban and Structural Entomology has an extensive information and warning piece out on the beasts — reprinted for you below the fold.

Look what else you can find:

Cicada hawks a month early – another sign of climate change?

July 2, 2009

Well I remember summer camp as a Boy Scout, annually at Maple Dell, a few miles up Payson Canyon, Utah.  Troop 17 camped the week of July 4th, by tradition.  Most other troops avoided that week so families could get together on the holiday — there would be half the usual number of Scouts, and we had a lot more opportunities to hit the rifle range, archery range, rowboats and canoes.  Over four years, we noticed that the annual cicada invasion would usually start near the end of that week, as the Utah heat started its march toward August records.  It was a good week to camp, to avoid the heat and the astounding noise of those insects.

As an Explorer, and junior camp staff member later, I spent entire summers at Maple Dell.  We’d start in early June, when the Payson River still ran icy from the snow runoff, and when our sleeping bags would be coated with frost in the morning.  Cicadas in July said it was warming.  Cicadas in August screamed it was hot — sometimes near 100° F, a dramatic shift from the frost just eight weeks earlier.

In Maryland, one year we lived through the confluence of the 13-year and 17-year locusts, which are related to cicadas. (Bug Girl?  You out there?  Help me out on these details.)  The adults would literally coat trees.  They’d mate and die, and fall to the street, where cars would smush them — driving was more treacherous than driving on ice.  What few predators there were — and the predators seemed awfully few in relation to the billion locusts per acre — would eat their fill, and then ignore the rest of the mob.  The locusts came earlier than the cicadas, as I recall — but still later in the summer.

A post I wrote two years ago has been getting a lot of hits. In late July 2007 I wrote of the return of the cicada hawks, here in Dallas.  Each summer since, about the time the cicada hawks return, people start cruising the web to find out how to get rid of them, mostly (don’t, they’re practically harmless).   As I watched the traffic counts, I noticed that I had posted it on July 20 back in 2007.  I wrote that the wasps had been around for about ten days, then.  Last year I posted a welcome to the wasps on July 8.

I saw my first cicada-killer wasp in 2009 about  June 10.  We didn’t have cicadas, then, that I could find.  The cicadas started buzzing on June 21, the first day of summer.  Our backyard is quite busy with cicada hawks right now, tracking down the cicadas and digging the holes in which to store the cicada zombies.

I hate to crash the denialists’ parties, but it sure seems to me that this cicada season thing is moving up.  The tilt of the Earth is still 23°.  The amount of daylight is the same.  What factors other than climate warming would cause these insects to come earlier each year?  What’s your experience?
