Small Rivulet
A delicate small moth found in damp habitats where hemp agrimony grows. The larvae feed inside the flowers. Has subtle grey and white wing markings.
Did You Know?
The larvae develop entirely within hemp agrimony flower heads, emerging only to pupate.
Viceroy Butterfly
Orange and black wings resembling the Monarch but with a black postmedian line across the hindwings. Once thought to be a harmless mimic, it is actually unpalatable too.
Did You Know?
It is a Mullerian co-mimic with the Monarch, as both species are distasteful to predators.
