I'd go with weevils to as most likely suspect.

Does the damange happen at night? Cockroaches could be responsible.

We have lot's of lizards and geckos in Florida and I've never known them to eat buds or foliage. Iguanas, however, will eat blossoms and fruit. Parrots will eat flowers too. Maybe someone's pet escaped.

Eating my buds too!
 

I searched the forum and saw this thread....exactly the same problem here. We have lots of Lizards here in SW Florida and that is the only critter that is able to find it's way onto my screen porch where my orchids are kept. I've not caught them in the act yet, but it's the only answer. 2nd bloom season in a row that I have lost bloom shoots and buds due to them. Wasn't sure of the solution until I saw the cotton suggestion on another post. Going to try it!

my best guess as I have had something similar and what I found was some small caterpillars or some kind of larvael worm/ or fly maggot. You got to get out there at night with a flashlight and see whats up after dark. I should have saved the worm but I have plenty of odd flies in and out around the greenhouse. While lizards dont eat the bloom or the bud, there isnt any rules against them taking a bit of it if it contains a meal ya know.:twocents:

I you want to stop the bugs you got to think like a bug :biggrin:

If it happens in the day time it could very well be paper wasps. Yellow jackets also eat flower buds. They have been known to cut the stalks of dalias. They are making nests. My poppies were decimated two years ago.
