Stems!

Bug Squad - Happenings in the Insect World   By Kathy Keatley Garvey  July 18, 2014

Just one word--stems.

Bees forage on the lavender in our bee yard, but sometimes you'll see them on the stems.

Male longhorned bees, Melissodes agilis, sleep together on the stems and it's fascinating to watch them stir in the early morning, wiggle around, and then buzz off--usually to dive-bomb any critter that's foraging on "their" flowers that they're saving for the females of their species.

But every once in a while, an early riser, a honey bee, will...

Karate Kick!

Bug Squad - Happenings in the Insect World   By Kathy Keatley Garvey    July 7, 2014

If you've ever watched a karate competition, you've probably seen the roundhouse kick, tornado kick, the reverse roundhouse kick or the flying side kick.

But have you ever seen a bee do that?

We were photographing sunflower bees on our Mexican sunflowers (Tithonia) yesterday, trying to catch the territorial dive-bombing. We were shooting with a Canon E0S 7D equipped with a 100mm macro lens. Settings: ISO, 1600. Shutter speed,  1/1400 of a second. F-stop, 10.

If bees could engage in humanlike conversation, imagine this dialogue:

"This flower is mine! Get off! I want my ladies to have that flower!"

"No, it's not! It's mine. I was here first! Leave me alone!"

For awhile, a large bee, a male longhorned bee, Svastra obliqua (as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis), appeared to be the "king of the mountain." It held its ground...er...floral resource.

Suddenly, faster than my shutter speed, a smaller bee of a different species, a male longhorned bee, Melissodes (probably Melissodes agilis, Thorp said) headbutted Svastra,  a scene reminiscent of a World Cup play.

One swift kick by Mr. Svastra and a surprised Mr. Melissodes shot straight up in the air, whirling end over end. 

Roundhouse kick? Tornado kick? Reverse roundhouse kicK? Flying side kick?

Whatever it was, the "bee master" won.

And he wasn't even wearing a black belt.
