🪲Meet the water lettuce weevil — native to South and Central America, and it only eats water lettuce🥬
🪲Here’s what they do:
Females chew tiny holes in the leaves to lay their eggs, sealing each one with a black protective coating. When the larvae hatch, they tunnel straight into the spongy leaf tissue, feeding from the inside out. That tunneling floods air-filled cells that normally keep the lettuce buoyant, until the whole thing waterlogs and sinks.
The full life cycle — egg to adult — takes about 4–6 weeks, and up to three generations can hatch in a single season. From what I’ve read, this tiny weevil can crash a full water lettuce infestation in under two years. I guess that’s quick?
Any water lettuce fans out there? Do you hate the weevils?
