Subject: Pathway identified for introduction of Pieris brassicae (Lepidoptera: Pieridae) from Europe
Publicada: October 02, 2002
Source: USDA-APHIS-PPQ Massachussetts
A large number (approx. 100) of viable pupae of Pieris brassicae (Lepidoptera: Pieridae), a large white butterfly, were found attached to the exterior of a shipping container from Spain in August 2002. Last instar larvae are known to seek walls and fences when 'wandering' prior to pupation; a convenient shipping container could therefore be assumed to provide an excellent substrate.

Pieris brassicae is a close relative of the cabbage butterfly (P. rape) which is established in North America.
