Caterpillars and Orchids

Picture of walnut caterpillars

Hi Dan,

My neighbor has these caterpillars around her patio. Just wondering if you knew what type they were. They look like they would cause a nasty sting!

Also, my orchids were chewed up by snails - should I cut the entire leaf off? Or leave the leaf?

Thanks as always!

These are walnut caterpillars – they do not sting.

For the orchids, if a leaf is over half gone and looks unhealthy, remove it. A healthy looking leaf that just has some holes in it is still functioning well and should be retained.
