Plants used as nectar sources by the Adult
Striated Queen Butterfly
Unfortunately we do not have much information
on the striated Queen butterfly as it does not usually come into our
area (San Luis Obispo County). We had one vagrant in our demonstration
garden. He was attacked by Monarchs who seemed to think him a threat.
In the picture on the left he is sipping from Asclepias
speciosa. This is a large tidy milkweed that looks
good in a garden setting. It has large attractive flowers.
Plants used by the Larva of the Striated Queen
The Striated Queen butterfly larva, like the
Monarch, feeds on true milkweeds Asclepias spp. However, they
also feed on climbing milkweeds, Sarcostemma spp.
One of the true milkweeds that the Striated
Queen Butterfly likes is Desert milkweed, Asclepias
erosa. This is a tall slender milkweed with very odd leaves and
white flowers. The leaves are alternate and they curve up around the
edges, forming nearly two inch deep cups.
