Making of a Monarch

At this time of year Monarchs (or Wanderers if you prefer) Danaus plexippus are quite prevalent and have been busy depositing eggs on one of the favourite food plants for their caterpillars, milkweed or cotton bush a couple of the many common names for an introduced weed Gomphocarpus fructicosa.
I found a few of the caterpillars busy devouring leaves on a small bush that I have let grow as a food source for these beautiful caterpillars.
