The larval stage of C. catalpae is known as the catalpa or catawba worm. When first hatching, the larvae are very pale, but become darker toward the last instars.The yellow caterpillars will usually have a dark, black stripe down their back along with black dots along their sides.
The tree is often sought out by fishing enthusiasts, not for the plant itself, but for a common parasite that is used as bait. The catalpa moth caterpillar, Ceratomia catalpae, is widely regarded as one of the best live baits, and the tree may be planted strictly for this purpose, and has earned the tree common names of worm tree, or bait tree.
Most Catalpa are deciduous trees; they typically grow to 12–18 metres (40–60 ft) tall, with branches spreading to a diameter of about 6–12 metres (20–40 ft). They are fast growers and a 10-year-old sapling may stand about 6 metres (20 ft) tall.

Catalpa bignonioides is a deciduous tree growing to 25–40 feet (7.6–12.2 m) tall with an equal or greater spread, [8] with a trunk up to 1 metre (3 ft 3 in) diameter, with brown to gray bark, maturing into hard plates or ridges. The short thick trunk supports long and straggling branches which form a broad and irregular head.

Cutworm larvae vary in their feeding behaviour; some remain with the plant they cut down and feed on it, while others often move on after eating a small amount from a felled seedling; such a wasteful mode of feeding results in disproportionate damage to crops.
Earthworms are shifting their ranges northwards into forests between 45° and 69° latitude in North America that have lacked native earthworms since the last ice age. [3] Of the 182 taxa of earthworms found in the United States and Canada, 60 (33%) are introduced species, these earthworm species are primarily from Europe and Asia.
