Saw this today...Most beautiful bug I've ever seen!
Was at work ( In Northern Florida ) and saw this little guy crawling around. Came home and researched WTF it was! (Other than GORGEOUS)
Here's what I found...
Syntomeida epilais Walker)
The adult stage of the oleander caterpillar is sometimes called the "polka-dot wasp moth." Wasp moth is the common name given to the subfamily of arctiid moths to which this species belongs (the ctenuchines) because of their resemblance to wasps such as the sphecids and pompilids. The moth's body and wings are a beautiful iridescent blue/green. Small white dots are found on the body, wings, legs and antennae, and the tip of the abdomen is red/orange. Male and female moths are quite similar in appearance, and have a wing span of 45 to 51 mm. These moths are slow-flying and active during daylight hours which contrasts them with other moth species which are usually nocturnal.
