"The Colorado Beetle is a beetle first described by Thomas Say, in 1824, from specimens found by him near the Upper Missouri. The larva feeds greedily on the potato, and having attracted notice in Colorado for its ravages among the crops of that esculent in the territory, it moved eastward year by year, till in 1874 it had reached the Atlantic seaboard. It is popularly known as the potato bug."&mdash;(Charles Leonard-Stuart, 1911)

"If the guide stops a moment all the followers halt; if he continues the route, they all hasten after him; if he makes a circuit, they all make the circuit also. Should they find a branch of fresh green leaves, they immediately prepare to feast upon it; the ranks spread themselves upon it, each one touching his neighbor, so that not a part of the branch escapes their depridations." &mdash; Goodrich, 1859

An illustration of a tent caterpillar cacoon. Tent caterpillars are moderately sized species in the genus Malacosoma in the moth family Lasiocampidae. Species occur in North America, Mexico, and Eurasia. Twenty-six species have been described, six of which occur in North America. Some species are considered to have subspecies as well. Although most people consider tent caterpillars only as pests due to their habit of defoliating trees, they are among the most social of all caterpillars and exhibit many noteworthy behaviors.

Orgyia leucostigma, the White-marked tussock moth, is a moth in the family Lymantriidae. The caterpillar is very common especially in late summer in eastern North America, as far west as Texas, Colorado, and Alberta. There are two or more generations a year in eastern North America (Wagner 2005). They overwinter in the egg stage. Eggs are laid in a single mass over the cocoon of the female, and covered in a froth (Wagner 2005). Up to 300 eggs are laid at a time. he larvae are brightly coloured, with tufts of hair-like setae. The head is bright red, the body has yellow or white stripes, with a black stripe along the middle of the back. There are bright red defensive glands on the hind end of the back. Four white toothbrush-like tufts stand out from the back, and there is a grey-brown hair pencil at the hind end. Touching the hairs will set off an allergic reaction in many humans (Wagner 2005). Young larvae skeletonize the surface of the leaf, while older larvae eat everything except the larger veins (Rose and Lindquist, 1982). They grow to about 35 mm.
