These caterpillars are big!

With that spike on the back, looks like maybe a hawkmoth?
@cathal My wife also agrees with Lime Hawk-Moth so that’s what we’ll go with. 😀
@cathal Could be. One of the first hits I get is the Lime Hawk-Moth, mimas tiliae. But there seem to be so many variants. And I didn’t see any other colors except for the bluish tint of the thorn.
