1 August 2019. Pheromone trap catches confirm WBC presence in a majority of agricultural regions across western, central, northern, and downstate NY as well as the Catskills.
NEWA WBC modeling indicates the threshold of 25% flight completion for egg mass scouting has been exceeded in the western, finger lakes, central, Mohawk River Valley, and Hudson River Valley regions of NY.
25% flight completion thresholds are likely to be exceeded by early next week in northern NY and western Catskill regions, and upland areas east of the Hudson River near Albany.
An important reminder that WBC estimated flight emergence is only applicable when presence has been confirmed.
