Insects and spiders (+ some other critters) close up

Oak sawfly larva, Caliroa sp, along with feeding damage on the underside of an oak leaf.  If you're so inclined, you can easily follow the larva's food as it moves through the digestive system.  The leaf tissue is taken into the body and remains green prior to digestion.  During digestion the food turns brown as it's broken down by enzymes and nutrients are absorbed from the gut.  Finally the food residue becomes darker and pellitized (water is reabsorbed) prior to excretion from the posterior end.

  • Larva of a spice bush swallowtail showing off his huge false "eye" on the enlarged thorax that is effective at creating the illusion to a predator that the larva is much larger than it really is, causing the predator to have "second thoughts" about attacking.  The real eyes are just below the yellow band that covers the head. check

  • Green stink bug showing the compound eyes and the two simple eyes just above.  These bugs have scent glands between their second and third set of legs and can produce a very obnoxious odor for protection against enemies.  Stink bugs suck juices from plants and can be economic pests.  check
