Arctic Bumblebee
A large, densely furred bumblebee with yellow and black banding adapted to extreme cold. Its thick pile of hair provides superior insulation. Queens emerge from hibernation as soon as snow melts.
Did You Know?
This bumblebee can maintain its flight muscle temperature at 30 degrees Celsius even when the air temperature is near freezing, thanks to its exceptional insulation.
Rose-stem Gall Wasp
A gall wasp that creates spiny galls on the stems of wild roses in North America. Each gall contains a single larval cell surrounded by hard woody tissue.
Did You Know?
Its galls often persist on rose stems for years after the wasp has emerged, serving as shelter for other insects.
