Finally some good news about the caterpillar outbreaks! Heather Faubert reports that Gypsy moth caterpillars have been dying by the thousands all over Rhode Island, thanks to a fungal pathogen, Entomophaga maimaiga, and a wet spring. Gypsy moth caterpillars started dying from Entomophaga mid-May. More died each week until the grand finale which occurred around June 23rd. It takes about 7 days for a gypsy moth caterpillar to die once it gets infected by the fungus; so 7 days after June 16 we started seeing massive numbers of gypsy moth caterpillars dying.
