Fall Webworm
A native North American moth whose caterpillars build communal silk webs on tree branches. It has become invasive in Europe and Asia.
Did You Know?
Unlike tent caterpillars, fall webworm nests enclose the foliage the larvae are feeding on.
Achilles Morpho
A medium-sized morpho with a bright blue band across dark brown-black wings. It flies rapidly through the forest understory in a distinctive bobbing pattern.
Did You Know?
Its blue band appears to flash on and off as it flies, because the brown undersides show with each wingbeat.
