There's not that many people doing hornworms out there
I've met the people here that supply and I can tell you that they're concerned
with keeping people happy over anything damaged by the shipper.
The feed is poured in and is usually quite secure, it takes a bit dislodge it.
next time, I suggest that you open up the box and inspect asap.
They're LIVE cargo
and should have been better handled by UPS (or ?)
Start a claim and contact the supplier right then if it's not right.
That way the shippers are encouraged to get their act together
by paying for the damage.
I've get a half dozen cups at a time without any problems
The problem seems to be with some bozo THROWING the live cargo box around the backroom at 3 am.
