BANGOR DAILY NEWS • May 20, 2025

According to a recent update from the Maine Department of Agriculture, Conservation and Forestry, browntail moth caterpillars are thriving in Brewer. The report states that, of the surveyed and monitored areas across the state, the invasive browntail moth caterpillars sampled in Brewer are developing faster than caterpillars at other monitoring sites. According to the state agency, the caterpillars sampled from the Brewer sites are roughly 20 percent larger than the caterpillars at other sites. The accelerated development means that the Brewer area is likely to see mature browntail moths earlier than other locations around the state.
