Insects rely on warm temperatures to grow, and thus their emergence and life cycle progression can be tracked by tracking the "heating units" that accumulate each day. This is referred to as growing degree days.
Growing degree days (GDD) are calculated by average the high and low temperature for the day and subtracting 50 (base 50). The positive remainder is added to the cumulative total of GDD. For more information on GDD and how to calculate the go to:…Continue

Books I use (and I use mostly books for initial ID):
