Greetings!

Thanks for your interest in the USA National Phenology Network's Pheno Forecasts this year, intended to assist you in indicating when pests were active in your area.

Due to technical difficulties, our forecasts for several species (apple maggot, Asian longhorned beetle, bagworm, bronze birch borer, eastern tent caterpillar, hemlock woolly adelgid, lilac borer, magnolia scale, pine needle scale, spongy moth, and winter moth) stopped sending in June of this year. If your location reached the requirements for activity after this date, you may not have received a notification this year. We apologize for the disruption. We are currently exploring options to fix these forecasts.

We want to hear your feedback on three of our most recent Pheno Forecasts. If you signed up for notifications for one of the species below, please complete the survey to let us know how the forecasts performed for you this year. Your input will help ensure that the forecasts are most useful to you.

Did you earn your Pest Patrol Badge this year?

Submit observations of pests six times in a year and you can earn the Pest Patrol badge featured at right. See it on your Observation Deck.

How do we forecast activity of pests?

Insect pest forecasts are based on USA-NPN Accumulated Growing Degree Day (AGDD) map products and published GDD thresholds. References for the published thresholds used to generate the forecasts appear on the individual species pages linked from our Pheno Forecast page.
