The new species that Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis, discovered on the Indonesian island of Sulawesi measures a whopping two and a half inches long.
That's the male "warrior wasp." The female is a little smaller. Just a little.
First thing folks say is "Wow!"
Next they ask: "Does it sting?"
Like all wasps, the female does; the male does not.
The male's jaws "are so large that they wrap up either side of the head when closed," Kimsey says. "When the jaws are open they are actually longer than the male’s front legs. I don’t know how it can walk."
Indeed--those jaws look like elephant tusks dragging on the ground.
Kimsey discovered the warrior wasp on the Mekongga Mountains in southeastern Sulawesi on a recent biodiversity expedition funded by a five-year grant from the International Cooperative Biodiversity Group Program.
The insect-eating predator belongs to the genus Dalara and family Crabronidae.
Kimsey says she's going to name it Garuda, after the national symbol of Indonesia. Garuda is a mythical half-man, half-eagle warrior, magnificent in combat.
Kimsey is a collaborator of a five-year $4 million grant awarded to UC Davis scientists in 2008 to study the biodiversity of fungi, bacteria, plants, insects and vertebrates on Sulawesi, all considered threatened by logging operations and mining developments. Much of the mountain was logged two decades ago and now there are plans for an open pit nickel mine, Kimsey said.
“There’s talk of forming a biosphere reserve to preserve this,” she says. “There are so many rare and endangered species on Sulawesi that the world may never see."
This is one they can see.

Gotta love those dragonflies in the family Libellulidae.
The Thunderbirds of the insect world, they perform amazing aerial maneuvers as they skim over water, catching mosquitoes, knats, flies and other undesirables on the wing.
But oh--occasionally they nail a pollinator.
A red flame skimmer (Libellula saturata) skimmed over our fish pond and pool last Saturday and picked on the pollinators. Well, at least one pollinator.
It grabbed a female sweat bee, of the genus Halictus, probably H. tripartitus (as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis).
Yes, they can even identify a mangled sweat bee in the mouth of a dragonfly.
And no sweat bee.

Have you ever stopped to admire a blossom and seen forceps protruding?
We were walking near Mrak Hall, UC Davis, on a hot summery afternoon and spotted a tell-tale sign: abdominal forceps, aka pinchers or pincers.
In a male earwig, the forceps are more widely spaced.
The most abundant earwig in California is the European eartwig, Forficula auricularia (family Forficulidae), according to entomologists Jerry Powell and Charles Hogue in their book, California Insects. However, it was not known in the state until 1923.
They describe the adult as about 12 to 22mm long, mostly brown with pale forewings and antennae. "The immatures and adults feed on a wide variety of substances, from flowers and green foliage near the ground to living and dead insects, including aphids."
This one seemed to be escaping from the heat.

You never hear anyone say "He's as cute as an earwig."
Or, he's as cute as a "lygus bug."
No. It's "Cute as a June bug," which could be any number of bugs, including the fig beetle (Cotinus mutabilis).
Over at the Bohart Museum of Entomology on the UC Davis campus, you'll see plenty of June bugs at a special open house from 1 to 4 p.m., Sunday, June 5. The theme is "June Bugs," and it follows on the heels of "Moth-er's Day," spotlighting moths. Admission is free.
The Bohart Museum, located at 1124 Academic Surge on California Drive, houses more than seven million insect specimens, plus a "living petting zoo" of Madagascar hissing cockroaches and walking sticks.
The museum also has a gift shop which includes T-shirts, sweatshirts, posters, jewelry and insect candy and the like.
A popular item is a toddler-sized t-shirt with praying mantids all over it, says museum director Lynn Kimsey, professor of entomology at UC Davis.
That's sure to get folks interested in entomology--or at least talking about bugs!

Do you brake for wasps?
We spotted a bumper sticker on the UC Davis campus the other day that read: "I brake for wasps."
It was parked in the Briggs Hall loading zone--Briggs is the home of the UC Davis Department of Entomology--so I imagine it was braking for wasps right then and there.
It was not a car owned by self-described "wasp woman" Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology at UC Davis.
But she wants one of those bumper stickers!
The colorful wasp below was foraging recently on an Indian hawthorn (Rhaphiolepsis umbellata 'Olivia') at the Benicia marina. Kimsey identified it as a "a solitary vespid, probably in the genus Stenodynerus. This is a male. The females feed on caterpillars."
Of these wasps: "They are pretty interesting," Kimsey said. "The males have the last antennal segment like a finger folded up against the adjacent segment. You can see it in one of the photos."
