Where are catalpa trees found?
The Northern catalpa’s modern native range is primarily the states of Ohio, Indiana, Illinois, Missouri, Arkansas, Kentucky, and Tennessee. Southern catalpa’s modern native range is primarily Georgia, Mississippi, Florida, Alabama, and Louisiana. However, there is overlap, and even some of the most knowledgeable plantsmen have a hard time stringing together an explanation of the difference in range between the two species. It is thought that before European settlement these two species occupied nonoverlapping ranges in their original wild state, with the Southern catalpa having the most limited geographic distribution of only central Alabama and Mississippi down to western Florida. Catalpa owes some of its geographic distribution to the expansion of railroads in the 1870s. It was planted in large quantities with the intention of producing wood for railroad ties. The trees are fast growing, rot resistant, and easy to drive a spike into. Unfortunately, the wood ended up being too weak to support rail traffic.

Common Names
Scientific Name
- Ceratomia catalpa(Boisduval, 1875) Order: Lepidoptera (butterflies and moths) Family: Sphingidae (sphinx moths)
Summary
- Catalpa worms are occasional pests that may defoliate catalpa trees during outbreak years. However, they are a native species that are attacked by a host of natural enemies, so control is often not warranted.
Distribution
- Catalpa sphinx are native to the eastern United States and can be found wherever catalpa trees occur from New Hampshire and Nebraska south to the Florida and Texas (Figure 1). This species has historically been found in Maine and northern New England but may now be absent from that region. Figure 1. Range of catalpa sphinx in North America. Map from Butterflies and Moths (20…
Description and Identification
- Like other sphinx moth caterpillars, catalpa worms possess a stiff "horn" near the end of the abdomen, which is relatively long, straight, and black compared to other species. Young caterpillars are mostly white with black spots. Older caterpillars are variable in color and can range from mostly yellow to almost entirely black, although most are black dorsally with a broad…
Host Plants
- Catalpa worms feed exclusively on trees in the genus Catalpa, including native northern and southern catalpa (C. speciosa and C. bignonioides, respectively) as well as non-native species like Chinese catalpa (C. ovata) that are occasionally planted as ornamentals.
Life History
- Pupae overwinter in soil around the base of the host tree. Adult moths begin to emerge in April and can be found through October. Masses of 100–1,000 eggs are laid on the underside of catalpa leaves. Caterpillars are present from May through November. Only one generation occurs in northern areas, including Pennsylvania, while up to five generations can occur in southern are…
Control
- During non-outbreak years, natural enemies often exert enough control on catalpa worms that additional control measures are unnecessary or even detrimental as catalpa sphinx populations, especially in the south where multiple generations occur, may recover faster than natural enemies and outbreak sooner than they would have. Healthy catalpa trees can withstand complete defoli…
Uses
- Catalpa worms are sometimes used as fishing bait, especially in the southern US. They are apparently an excellent bait for largemouth bass and catfish and some dedicated fishermen have been known to drive many miles or plant small groves of catalpa trees in order to secure a ready supply of catalpa worms. A patent for preserving live catalpa worms for bait was filed in 2003.
