I recognized that there are a few minor shortcomings, but no tree is perfect. Thus far, the damage is barely noticeable, but that will soon change as the ravenous caterpillars increase their size and appetite.Ĭatalpas have long been one of my favorite trees. The caterpillars consume the entire leaf with the exception of the main leaf veins. The caterpillars were 2nd instars when I found them on Monday however, these native moth caterpillars develop rapidly.
I came across a collection of first-generation catalpa hornworms ( Ceratomia catalpae) feeding on a southern catalpa ( Catalpa speciose, family Bignoniaceae)) planted in a county park in southwest Ohio.
