29 July 2019. Pheromone trap catches confirm WBC presence in western and central NY, as well as the Champlain and Hudson Valley regions of eastern NY.

NEWA WBC modeling indicates the threshold of 25% flight completion for egg mass scouting has been exceeded in western NY, the Genesee Valley and Finger Lakes, and most of the Hudson Valley region.

Central NY, Lake George, southern and eastern shores of Lake Ontario are likely to exceed the 25% flight completion threshold by Wednesday.

The St. Lawrence, Champlain, and Catskill regions are likely to reach the 25% threshold by weeks’ end.

An important reminder that WBC estimated flight emergence is only applicable when presence has been confirmed.
