6070 Hi. Ann in Winnipeg it’s July 11.2017. Found these two guys in my yard? What are they??
These are caterpillars of Abbott’s sphinx moth, Sphecodina abbottii (Lepidoptera: Sphingidae); see https://tinyurl.com/y9glgn73 for more detailed information. The one on the left had been parasitized by a wasp in the family Braconidae; after the wasp larvae finish growing, they chew through the caterpillar’s skin to spin their cocoons. Adult wasps eventually will emerge from these to seek out more caterpillars. Ed Saugstad, retired entomologist; Sinks Grove, WV.
