Nicely illustrated poster and one-page handout that introduces this subject. Prepared by Andy Hamilton, familiar to BugGuide contributors, and includes photos by a number of BugGuide members. Important information in English, French, and Spanish.

Excel spreadsheet added to the page
the most valuable piece of info that the page provides --at least for me: now i can add relevant data to many a guide page, and update Beatriz's list!
Legend to the columns:
A/B = Genus/species
C/D = date and place of first introduction
E/F = date and place of any subsequent introduction
G/H = same, if a third introduction (e.g., on east/west coast, Gulf coast)
I = remarks: host, pest/rarity status, range
J = source of infestation
K = family
L = notes
M = area of introduction (use for sorting by country of interest)
N = photo (or drawing) available?
