biosystems: Painful Symbiosis
These sphinx moth larvae have a special relationship with catawba trees (a.k.a. catalpa trees) since these trees are their only food source. 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. Like many things in nature, the catalpa tree and worm have a special one-on-one relationship.
In fact, nothing really even goes in the trees unless you put a bird feeder in them. The trees don't seem to be in any danger of extinction here, but I've never seen the worms.
Symbiotic Relationship between Catalpa Worm and Braconid Wasp by Lucas Zuehl on Prezi
Our house is surrounded by catalpa trees. They are very old and have survived many lighting storms and are almost 70' tall. We have worms every year. We have always wondered where the worms come from. All together we must have 25 catalpa trees on our property. They are wonderful shade trees but are rather messy.
They make a wonderful canopy over our back yard, one year we had to move the picnic tables out from under the trees because of the worm dung.
We love our trees and are very sad when we have to lose one because of lighting.Catfish Candy - The Catalpa Worm
One of the trees in the back yard must be at least 20' around and is 75' tall. We have no idea how or where the trees came from everyone we talk to say they have always been here.

We have lived here for 45 years and they were mature trees when we moved in. They were given to me by an aunt that had mature trees around their now for sale property.
I am sure that those trees are relatives to the original trees. The home was built in the 's. There are several catalpa's around that old house. I don't ever bother the worms as I assume they have a purpose. Now I understand why I leave them alone. We moved back to our family farm after my husband retired from the Air Force.
I guess I had forgot about all the different trees on the property.
Catalpa Worms and Parasitic Wasps
Well, Catalpa trees are among a few of them. We have been trying to refurbish the He worms by transplanting. For over 3 years we have traveled to Mississippi to buy worms, bring them back to our farm and let them eat away.
- Leave Those Catalpa Worms Be
The first year the pupa died. The second and third were devoured by ants and then wasp. We are traveling back from Mississippi as I type. We have an ice chest full of these giant beautiful but peculiar looking creatures. Our area has been rid of the worms and trees almost completely. Onc the worms are gone the trees aren't beautiful or fragrant. Most people hav had the trees removed. The tree limbs can't be burned.
The wood it produces is absolutely beautifutiful. Hoping this times the charm. We will be glad o keep you posted. I've recently moved back into my childhood home.
We have had a large "Toby" tree here ever since I was young. Last week my mom and I noticed these worms munching on all the leaves and we were worried that we were gonna lose that beloved, old tree. I'm so happy that these worms and that tree have a symbiotic relationship and that the Toby will thrive from it! Thank you for the good Mother Earth news!!! We've lived here in southern york pa for 18 years and have never had worms before.
They ate leaves of catalpa trees, usually small ones, and when you found the worms they were in large numbers. 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 Sea Anemone protects the Clownfish from predators by using its tentacles to paralyze predators with Cynoblasts shocks and then ingesting the predators. Clownfish defend the Anemone from Butterfly Fish that feed on Anemone. The Catalpa Worm is being fed on by tiny wasp larvae. The adult wasps sting the caterpillar, injecting their eggs.
The eggs hatch and devour the caterpillar from the inside, being careful not to disrupt any vital functions. Eventually they emerge and spin cocoons of silk in which they transition from larvae to adult. Another symbiotic relationship occurs between humans and mosquitoes. Mosquitoes feed on human blood and in turn create an irritation on the skin at the site where the mosquito fed on the human. Mosquitoes can also transmit various viruses such as the West Nile Virus.
The Malaria parasite is also transmitted through a mosquito bite and can be deadly to a human. The ostrich and the zebra have unique relationship.
