Lost my first agave to these pests today. I've been watching this plant do strange things, so I knew something was up. Today I pulled on a leaf and the whole plant toppled over.
No pics - I wasn't in the mood to do anything but eradicate grubs. GRUBS. Little writhing monsters. Many where tossed onto the lawn for the mockingbirds to harvest.
So now I have to keep a guarded eye on the rest of my agaves. I suspect the weevils target the plants that are ready to bloom and are building up reserves to send up that stalk.
Humans know this is the best time to harvest agave, and do so to make tequila - among other uses - so why would the weevils be less savvy?
So I'm posting this for reference:
