Following in the footsteps of the movement to knit sweaters for penguins, the David Suzuki Foundation announced the #Knit4Monarchs campaign, with tongue firmly in cheek.
"You can give the butterflies the warmest possible welcome by knitting a DIY monarch chrysalis in support of the David Suzuki Foundation's #knit4monarchs campaign," read a statement on the foundation's website.
There's even a #Knit4Monarchs Pinterest board for people looking for inspiration.
The David Suzuki Foundation doesn't actually need people to knit chrysalises for butterflies. Monarch caterpillars are quite capable of making their own, thank you very much — provided they have milkweed plants to eat.
And that's the real purpose behind the #Knit4Monarchs gag: to get people to plant milkweed seeds to give monarchs a food supply and a home.
