Monarch butterfly eggs are somewhat difficult to find in the wild. Since it only takes 3-5 days for eggs to hatch, timing is crucial. The best sign is to watch for adult Monarchs stopping at milkweed plants. A female will usually lay only one egg per milkweed plant to ensure enough food for each larva.onarch butterfly eggs are somewhat difficult to find in the wild.

All you need to do is have swan plants â and quite a few of them â and some warm weather. Firstly we know that the basic timing of a Monarchâs life cycle is: So from the egg to adult stage(s) can take as little as 23 days (4+9+10), and this would be in the optimum conditions, i.e. a full 23 days of hot summer sun. Bear in mind too, that not every egg is going to become a butterfly â some will be food for other species or even contribute to your garden detritus.
