Re: Weevils

Well, you've got a name, and presumably you've seen the weevils as well. Try www.bugguide.net and search using the latin name - if they're present anywhere in the US, that site will have a more reliable distribution map for them. They'll also have comments from various amateur and professional entomologists as to diet etc. And if all that fails, you can send an email to the site's owners, who are pro entomologists and will likely be able to point you in the right direction. You can also email them to ask about aquatic/semiaquatic domestic weevils with a prediliction for Lemna.

Best of luck!
Elizabeth (Ambato, Ecuador - incidentally, we have weevils in the Lemna here too.)
