True Bug Gallery
The world of true bugs includes a large varitey of amazing insects. Some of them are large and others are so tiny you can hardly see them.
Shield Bug, Acanthasoma hamorrhoidale (left) brightly colored to warn predators of their bad defensive smells; females care for their young nymphs. Leaf-footed Bug, Coreus marginatus (right) suck plant juices and give off a horrible smell if handled. Photo credits: Velela and Richard Bartz
Aphids (right and left). So tiny that they can be blown on the wind for 100s of miles. They suck sugary juices from plants and are often defended by ants that milk them of their sweet liquids. Young aphids are born alive and in some seasons are all females produced without mating with a male. Photo credits: Sanjay Acharya and Michel Vuijlsteke
Cicadas (left) are large and suck plant juices, often from tree roots. The adults sing ear-splitting trills and ringing calls that are most often heard on warm afternoons and evenings. Leafhopper (right) are small bugs, some of which cause great damage to potatoes, apples, beans and clover by introducing disease when they suck the plant juices.

Lethocerus americanus water bug (left) lives in water and is large (up to 4 inches long); it eats other insects, salamanders and small fish in streams and ponds. Its bite can be painful. Notonecta glauca, Backswimmer (right) swims upsidedown, as if it was in a backstrock swimming competion. Photo credits: The High Fin Sperm Whale and Holger Gröschl
Cimex lectularius bed bug (left) is a flightless species that hides in mattresses and cracks in the wall to sneak out at night to painlessly suck blood from sleeping people. Milkweed bug (right) is one of the few insects that can tolerate the extremely poison sap of the milkweed plant. It uses this poison in its body to protect itself from birds and other predators, and its bright color advertises a warning. Photo credits: CDC and Jose Luis Cernadas Iglesias
