fisherwr2 > View of the head of a large leafhopper (~ 13 mm) showing the piercing mouthparts, the sharp needle-like structure between the front legs. The anterior structure that looks like a surgical mask, characteristic of leafhoppers and cicadas, encloses muscles that help suck plant liquids into the insect. This mechanism is called the cibarial pump.
fisherwr2 > Anterior end of a clownlike leafhopper, Graphocephala versuta (Homoptera: Cicadellidae). Length of insect is about 5 mm.
fisherwr2 > Exoskeleton of a last instar leafhopper on the underside of an oak leaf. Similar to other exmples in this gallery, the mouthparts are imbedded into the main vein to anchor the insect to the leaf. In addition, the six legs are grasping the sides of the vein to further improve attachment to the leaf. This makes it easier for the adult to separate from the old skeleton. The split along the head and thorax is where the adult literally walked out of its' own skin. The oval structure lateral on the thorax contained the folded-up wings. The new adult was white, soft, and vulnerable until the body shell hardened and the wings were completely unfolded and ready to support flight.

fisherwr2 > Cast skin or exuvia of a leafhopper (Hemiptera: Cicadellidae) with mouthparts embedded in plant's main vein to anchor the old skin and allow the insect to free itself more easily
fisherwr2 > Cast skin or exuvia from a leafhopper, Paraulacizes irrorata (Hemiptera: Cicadellidae) on the underside of a leaf. Note the piercing mouthparts embedded into the leaf's main vein, which anchors the insect and allows the next stage to more easily shed it's old skin
