When did it suddenly become cool to hate everything? It's a growing problem, especially in the entertainment world, and no one benefits from an increasingly hard to please, pessimistic audience.

A quick question if you would be so kind; I've always wondered about how those dark 'eye' spots on their eye areas worked. Whenever I looked at a mantid, they would always seem to be arranged so that it would appear to be staring directly at me, regardless of what angle I viewed them in. Is this an actual function of the eyes they use to look at things (Sortof like how we are able to move our eyes), or is it just an effect of the light shining on it (assuming that mantids have eye arrays like many other insects)?

the dark pupil-like spot is a kind of simple illusion - and a result of construction of the compound eye. as you probably know, compound eyes are made of tiny tubes (ommatidia) with reflective inner walls and some pigment containing receptor cells on the bottom. because an insects eye is more or less spherical, the tubes are concentric. when you look at it, you see the dark bottoms (the cells absorb light) of only those tubes that are aligned with your eyesight. so, of course the dark spot follows you, but it doesn't mean the insect's attention does so too.
delightful!
