fisherwr2 > Simple eyes located on top of this wasp's head, between the multi-faceted compound eyes. The next image shows their location a bit more clearly. The simple eyes cannot focus but do detect changes in light intensity, as occurs during sundown and sunup. This triggers the insect's activity patterns - eg some insects are active at night, while others, during the day. Note the sensory hairs just below the lens of each eye.
fisherwr2 > Tiger beetle (Coleoptera: Cicindelidae), member of a group noted for its brilliant metallic colors. The adult is a potent predator as indicated by the deadly overlapping mandibles
fisherwr2 > Midge (Diptera: Chironomidae) showing plumose antennae characteristic of the male. The feathery antennae provide a tremendous surface area for sensors that are able to detect minute amounts of chemicals produced by the females. Apparently there also are sensors that can detect vibrations in the air produced from wing movements of the female. Both are critical to finding a mating partner. This specimen is about 7 mm long. Midges resemble mosquitoes but do not bite. Midge larvae are similar to mosquito larvae and form an important part of the aquatic food chain.
