The Catalpa Worm is affected negatively because the Braconid Wasp lays it's eggs in the Catalpa Worm and when the eggs hatch they feed on.
Catalpa Worms and Parasitic Wasps
Due to the importance of these associations, many efforts have been made to characterize the communities down to the individual members. However, most of these efforts were either based on cultivation methods or relied on the generation of 16S rRNA gene fragments which were sequenced for final identification. Unfortunately, these approaches only identified the bacterial species present in the gut and provided no information on the metabolic activity of the microorganisms.
To characterize the metabolically active bacterial species in the gut of an insect, we used stable isotope probing SIP in vivo employing 13 C-glucose as a universal substrate.

This is a promising culture-free technique that allows the linkage of microbial phylogenies to their particular metabolic activity. This is possible by tracking stable, isotope labeled atoms from substrates into microbial biomarkers, such as DNA and RNA 5.
Subsequent molecular analysis of the separated nucleic acid isotopomers provides the connection between metabolic activity and identity of the species. Here, we present the protocol used to characterize the metabolically active bacteria in the gut of a generalist insect our model systemSpodoptera littoralis Lepidoptera, Noctuidae. The PubMed Central Numerous invertebrate species belonging to several phyla cannot synthesize sterols de novo and rely on a dietary source of the compound.
We have isolated SCPx protein from Spodoptera littoralis cotton leafworm and have subjected it to limited amino acid sequencing.
You caught them, put them in a cage, took them out on the lake for bluegill, and that was as far as my thinking went. Not until college, in fact not until graduate school, did my thoughts go back to catalpa worms.
I saw them on trees at the edge of the Purdue campus, and at long last realized that they were, as should be obvious from the photo, caterpillars.
Furthermore, the single long spike on the end of the abdomen led me to the sphinx moth or hummingbird moth family, as this characteristic is found on larvae of nearly all species in that family, and not in others. The catalpa sphinx moth is strictly nocturnal, a generally nondescript brown color though with the long narrow wings and heavy body characteristic of the Sphingidae.
I knew from dendrology class that catalpa belongs to a plant family that is mainly tropical. In fact catalpa is native only as far north as Kentucky. Those in northern Indiana and Illinois have been introduced. The catalpa sphinx has followed the tree to northern Indiana, but I have not seen them in northeastern Illinois.
That chemical relationship the caterpillars have turned to their further advantage by using them for their own protection. Catalpa worms are conspicuous.Capital Naturalist: Catalpa Sphinx Moth Caterpillar with Braconid Wasp Emerging
My reading revealed that this is one of the few members of family Sphingidae that lay their eggs in clusters rather than scattered singles.
They are not completely safe, however. Often you encounter caterpillars like this, covered with the cocoons of a parasitic wasp.
