Grapeleaf skeletonizers

The grapevine has been in the garden for about 10 years. Infestation started 3 years ago. Ducks are only 4 months old.
 
The grapevine came from a local reputable nursery. The ducks came from a well known farm in N.California.
 
Wow, that's a good question. I know that Monarchs, for example, have toxins in their bodies.

But apparently tomato horn worms are okay.


I see the need for a new kind of encyclopedia - the encyclopedia of edible invertebrates!


Okay, someone already did this for the Pacific Northwest.

@Amiga , I wish my ducks could eat the tomato hornworms but I've read that since the tomato plants (in the nightshade family) are poisonous to ducks, and the worms concentrate the plant toxin in their blood, ducks cannot eat the hornworms. It's too bad because their big juicy sizes would've been good eating for my ducks.

@Newbee58 , thanks for the idea. I didn't think about searching info about the grapeleaf skeletonizers carrying parasites but that's a good thought. I was more concerned about any toxicities that bright-colored worms might cause because mother nature provides that as a defense mechanism against prey..
 
Update.......So I fed them the caterpillars and they loved it. They're still alive and quacking so it's safe to say the caterpillars are fair game.

Thank you for updating, this is goood to hear. I have 2 young ducks and grapevines I planted 2 years ago. There are no bugs yet, but this is good info to know for future. I have read that most farm animals won't eat anything that is poisonous to them. They might take one bite and never touch again.
