Linda McMulkin, horticulture coordinator for Colorado State University Extension of Pueblo County, said the spring moth population usually experiences a wild population explosion only after a wet summer and fall that's followed by a mild winter.I've been seeing more of those smaller, tan moths that normally invade in May. Should look them up in the insect field guide.
It's been bone dry in these parts for some time, but the mild winter and earlier spring temperatures may have allowed more of last fall's eggs to survive and take flight in search of a sweet buffet . . . . What can miller-hating humans do about the flitty, nasty creatures? Not much.
