Dorcaschema alternatum
Small Mulberry Borer
Dorcaschema alternatum is a cerambycid beetle native to North America, commonly known as the Small Mulberry Borer. It was first described by Thomas Say in 1824, originally placed in the genus Saperda. The species is strongly associated with mulberry trees, specifically Celtis-leaf mulberry (Morus celtidifolia), which serves as its larval host. It is widely recorded across the United States and southern Canada.
Hyphantria cunea
Fall Webworm, Fall Webworm Moth, American White Moth
The fall webworm (Hyphantria cunea) is a moth native to North America, ranging from southern Canada through the United States to northern Mexico. It is best known for its larval stage, in which caterpillars construct large silken webs on the terminal branches of host trees during late summer and fall. The species exhibits two color races that vary geographically: white moths with black-headed caterpillars predominate in northern populations, while spotted moths with red-headed caterpillars are more common in the south. Accidentally introduced to Hungary in the 1940s, it has become a destructive invasive pest across Europe and Asia, particularly in China where it is known as the 'North American White Moth.'
