Did you know … Monarch Butterflies are poisonous?
According to the Australian Butterfly Sanctuary website, Monarchs eat poisonous milkweed during their larval stage, which is stored in the body.
This poison, known as cardiac glycosides, causes predators to vomit, although it rarely causes death.
The brightly hued wings of the Monarch Butterfly acts as a “warning sign” to deter hungry predators.
Have you seen many Monarchs preparing for their late summer southern sojourn at one of Cataraqui Conservation’s properties or along the Cataraqui Trail?
