Update Egg-Dumping
Journey North

Monarchs sometimes arrive in the spring as milkweed is just beginning to emerge. When milkweed is in short supply, a monarch may lay more than one egg per plant or leaf. This is called "egg dumping" and is a sign that milkweed is in short supply. If milkweed were plentiful, monarchs would not lay so many eggs so closely together.
