 Insect MouthpartsThough the mouthparts of arthropods all developed from the same basic form, different species have evolved unique structures adapted to suit various styles of feeding, such as chewing, lapping, and siphoning. For example, the mouthparts of aphids are suited to piercing plant tissue and sucking up the sap. Butterflies and moths have siphoning mouthparts that form a long proboscis which is coiled at rest but can be extended to suck nectar from flowers. What type of mouthparts do arachnids have? More...

Spiders, hmmm? Can't say I ever actually studied one's mouth that closely. I know they inject a venom to help pre-digest as well as kill or at least paralyze their prey, which can sometimes be dangerous to us large critters, when they mistake us for chow {see black widows, brown recluses, funnel webs, and some species of tarantula, among others}. The fangs are usually at the front and pointing downward from the mouth area, but that's about the extent of my study of their mouths.

The fangs point 'downward' in true tarantulas, but in most spiders, the fangs work side to side in a pincher-like fashion. The attached VERY generalized sketch shows the more common spider fangs on the left, like the black widow, wolf spiders, etc. and on the right those found in tarantulas.

But spiders are not technically insects at all, right?

The guy has a PhD in Entomology and I have a copy of a book he has written on the subject; what would he know? ;-)

TFD has it's very own, on call, resident expert on things that 'bug' you. I've read bugdoctor's book; it is very interesting and the information is applicable to a much larger area than Georgia. From: http://www.amazon.com/Hey-Bug-Doctor-Insects-Georgias/dp/0820328049

The jaws of a dragonfly nymph are quite terrifying. And lightning fast.
