I'm interested in hybrids, I've done one cross with a male hyalophora euryalus and a female hyalophora columbia and fed the larva on cherry- just cherry, a grafted multi species cherry. All went well, and the moths should hatch this spring. What I'm wondering, is with other closely related species, does it matter in the crossing to the larva accepting a particular food? For instance, if I cross graellsia female with luna male, will they accept pine only, or liquidamber? The heart of the question is I think I read somewhere that hybrids accept the food of the female. Is that accurate? kevin |

Hello Kevin,
no, that's not correct - in sphingid crossings, the newly hatched caterpillars almost exclusively adopt the male's forage plant.
In this way, nature independently prevents such mismatches.
I mean, with Saturnids is the same. The crossing A. luna ♂ x A. dubernardi feeds on Juglandaceae.

With few exceptions, my feeling about hybridizing is there's not a lot to be gained. My euryalus x columbia looked more like columbia, and I didn't really expect anything dramatic to begin with, the pairing was just happen chance. Certainly, it's interesting but it's basically a lab created animal, although I am still trying for the lab created dubernardi or isabellae cross. |
