A small number of eastern tent caterpillar moths were captured in traps during the period of July 16 - 17 but moth flight, and associated egg-laying, should be nearly over for this season.
Females are reproductively mature when they leave the pupal stage and usually mate within hours of emergence. Eggs are laid soon after that. The moths cannot feed and live only a few days.
This means that all eggs should be laid by mid-August. This is a very conservative estimate, egg laying should be completed some time before that.
