Description
Another early morning image. The damselfly was probably wondering if I stay crunchy in milk...Those three round red "eyes" in the middle of its head are actually light detectors, and since they are arranged in a triangle the critter can use a simple form of triangulation to determine the speed and angle of an attacker, like a bird or that jerk with a camera, so it knows which way to duck. One of the reasons why I shot this critter so early in the day is that it's almost impossible to shoot them at high magnification at any other time.
Tech specs: Canon 40D (F10, 1/250, ISO 100) + a Canon MPE-65mm macro lens (@5x) + a diffused MT-24EX macro twin flash (-2/3 FEC).

Thanks
Those are basic light sensors, and since they are in a triangle the critter can use a simple form of triangulation to determine the speed and direction of an attack when a shadow passes over it.

Insects are so cool! It's amazing how complex some of the smallest critters are!

super cool! I love the golden eyes! I wonder how well the three secondary eyes in the middle of his head see?

Most insects have them, and it's the reason why you can't cast a shadow over if you're trying to get close (they'll just take off).

Tell her from me that you don't. Humans turn into raisins in liquid...

This face is definitely a nightmare if it shows up in my dream. It looks as if there were a smaller head in the center of its big head. Flowers are definitely prettier.

...but flowers are not as challenging

Yes and No. Flowers stay still, but there are elements of challenge to bring out the unique character and beauty of each species. And, one can never get tired of an ocean of different flowers. Of course, I wish I had your skills, but I'm aiming for it.

I was teasing you -I think flowers are some of the most difficult subjects that I've shot. It's not easy task to pull a good composition out of a simple daisy...
