Amazingly interesting cat for such a boring looking adult moth- unfortunately sphinx moths do a lot of damage to ornamentals.

I added a photo of both a brown and green tersa sphinx cat. They are good looking cats :o) Our local butterfly parks plant plenty of nectaring and larval host plants so it's always nice to see their efforts paying off :o)

One of the local nurseries calls me up periodically - seems their customers come in with jars of 'worms' they find eating their plants and want to know how to kill them!

Am always puzzled why folks want butterflies in their yard then complain about the 'worms' - it's called the cycle of life.

It's a good thing the guys at the nursery just about have me on speed-dial :o) They call me up and I go collect the caterpillars to raise and release them in my yard.

Will say Tersa cats are voracious eaters and they can strip penta plants to the stem...but the pentas always come back with new foliage :o)

And for all those who raise and release butterflies and moths...we know to always have plenty of the larval host plants on hand :o)

This is some very cool garden character. Sure they do "damage", lol... It's called sustenance! Every caterpillar requires a host plant in order to become a butterfly or moth. The main favorite of the Tersa is Penta, and they are actually quite picky. The cats can always be moved out of the main "show" garden to some potted plants in a less visible location.
These are very fun cats to raise, especially if there are any children around to track the stages with. Their cartoonish faces are way too cute not to love!! When they are ready to pupate they will crawl down into the leaf litter below the plant. This pupa can be collected to await it's emergence. That will generally happen sometime after midnight on about day 10-12. Like the majority of moths, the Tersa Sphinx Moth is nocturnal. They can usually be observed nectaring/pollinating the deep flowers right after dusk. Pollinating such deep flowers makes them a very beneficial character in the garden.

Was sitting outside one late night. They like to rest near an outdoor light on the house. I went to pet his wing while he was resting on the ground and he turned around, started to vibrate his wings real fast and it sounded like a Bee sound, then I got up and moved away slowly and he started to walk after me, following my every move, lol. So I decided to get away from him and go back indoors for the night.

About a month ago, while weeding around the edges of my lawn, I found a chrysalis of what turned out to be the tersa sphinx. I was surprised to find it just laying in the grass and assumed it must have blown off a tree or bush. I now know that these moths pupate underground or under leaf debris. A day later, perhaps I wouldn't have found it!
I waited patiently for a month with the chrysalis in a glass jar. Finally, two days ago the color changed to a darker brown and this morning the moth eclosed--while I was away from my desk, of course. It was a wonderful experience and several of my coworkers were just as excited as I was to watch its wings dry and its full color appear. When its wings were working, we took the moth outside and released it.
