However aphids do produce a fresh substance address honeydew ( coveted by ants ) which can run to an unattractive ignominious surface increment called pitchy mold .
Aphids can increase quickly in numbers and each female can produce up to 250 springy nymphs in the course of a calendar month without pairing .
