"Asian lady beetles - Harmonia axyridis - aren't native to Illinois but were introduced to the United States to deal with aphids on pecan trees and soybeans, according to the Web site.
Because Illinois has a lot of soybeans, the beetles flourished and multiplied, said Jeffrey Davidson, plant health safeguarding specialist for the USDA plant protection and quarantine department.
"And, once they're brought in, they're here - they're here," Davidson joked, adding that his department of the USDA isn't responsible for the Asian beetle infestation, and the part of the USDA that dealt with the initial importation did so "many, many years ago."
