Mile-a-minute weed

Speaking of the Polygonaceae family, another roadside discovery that summer was something called "mile-a-minute weed" -- Persicaria perfoliata -- a fast growing invasive weed (as the name suggests) hailing from tropical Asia, possessing distinctively triangular leaves and barbed stems that spread as a vine over other shrubs. Evidently it is popular with certain bugs, who turn the leaves into swiss cheese.

  1. They look like green, swiss cheese moths.

  2. To me they look like either green tortilla chips or triangular slices of green swiss cheese.

  3. Yes, I agree, but there is one particular leaf that really looks like a moth - top photo, on the left.
