(Photo on right is the White-faced Meadowhawk, Sympetrum obtrusum, here trying to stay cool by pointing his abdomen at the sun and thereby minimizing the area being illuminated and heated. - an example of insect thermoregulation by behavior.   This perching position is called the "obelisk", and is seen in a number of dragonflies.  I titled this picture "Firecracker" - the red-hot flower and red-hot dragonfly almost make you break out in a sweat just looking at them! Taken Aug. 1998 in Nebraska on a 105 degree day by Roy J. Beckemeyer. )
