Introduced Pine Sawfly
A European sawfly introduced to North America that feeds on white pine and other five-needled pines. Larvae feed gregariously and can heavily defoliate trees.
Did You Know?
It was first detected in Connecticut in 1914 and quickly spread across northeastern North America.
Fierce Big-Headed Ant
A widespread tropical ant and minor invasive species with clearly dimorphic workers. Majors have disproportionately large heads used in colony defense. Colonies are aggressive and fast-growing, often dominating disturbed tropical habitats.
Did You Know?
Despite being one of the most species-rich ant genera with over 1,000 species, Pheidole remains one of the least studied.
