Butterfly Club survey
Nine members of Massachusetts Butterfly Club surveyed on base April 29.
They found the caterpillar of the grammia phyllira tiger moth, which is
listed by Mass. conservation officials as endangered. Westover and the
immediate area is the only place in the state it is found. They also found
149 rare frosted elfin butterflies, common tiger beetles and a common snake.
