This crazy-looking creature is the larva of a brown lacewing (Micromus species). I found it hanging out on a lily leaf in my garden. Lacewing larvae use their curved mandibles to capture and consume soft-bodied insects like aphids, mealybugs, young caterpillars, beetle larvae, mites, and others. When mature, brown lacewings look much like their green cousins only slightly smaller and with brown coloration.
