Mystery Picture #24

(Mystery Pictures)(Mystery Pictures)


The Eyed Click Beetle is known for its ability to catapult itself into the air. An overturned beetle will make a sharp clicking noise as it flips itself into the air trying to right itself. The insect extends its head and prothorax backward and then quickly straightens its body. The straightening produces the click and propels the insect into the air. The two large "eye" spots on its thorax easily identify this species. Adults are typically associated with decaying wood and larvae are found in the soil feeding on plant roots, seeds, and other insects. The larvae can be serious agricultural pests of potatoes, wheat, corn, cabbage, cauliflower, radishes and cotton.

See riddle number 14 for a little poem about the click beetle!

Extra credit! What is the common name of the larva of this insect? Answer: Wireworm


This unusual green larva is a Syrphid larva. It feeds on aphids. (Note: it has an aphid in its mouth in the picture.) It crawls along the leaf surface to find its prey. Although it does somewhat resemble a caterpillar, it has no apparent head or feet. This species is not a plant feeder and causes no damage, in fact, it is a beneficial insect in that it preys on aphids which often can be very destructive to plants in the garden or field. The adults of this insect often resemble bees or wasps but they do not bite or sting.
