This monarch ate the leaf it was standing on. It took only 20 minutes! Can you find two? There are two caterpillars in the picture below. Monarchs can grow this much in only two weeks! A monarch grows 2, times bigger while it is a caterpillar. The Chrysalis Next, the hungry caterpillar turns into a chrysalis. A monarch is a chrysalis for days. The butterfly's beautiful orange and black wings appear the day before it is born.
The changes that happen inside a chrysalis are like magic. Lincoln Brower. The Adult This butterfly just came out of its chrysalis. Sign In. Join as a Pro. Houzz TV. Houzz Research.

Okay, you asked how long it takes for Monarch eggs to hatch, right? Keep us posted on your eggs, ficus-spider-man! OH, and also keep in mind that some eggs are NOT viable. I clean the 'easy' one every time I use the dryer. About once a month I use a long wand like flexible brush to clean as far down into the vent as possible.
I also use the wand attachment on the vacuum to clean as far into the vent as possible once a month. I became diligent about this after seeing the Fire Chief of a small town on television talking about it. HIS house burned to the ground because neither he or his wife ever deep cleaned the dryer vent.
Made a huge impression on me! Sister does not agree with my pillows not matching Q. If you do find an egg, it is best to collect the entire plant, and put its stem in water as soon as possible. If necessary, you can just take the leaf on which it is resting.
If Monarchs are reared in captivity, females will lay dozens of eggs on a single plant. Keep the plant stem in water. It may last longer if you cut the end of the stem just before putting it in water. If you have just taken the leaf, keep it on a moist paper towel or filter paper in a petri dish or any other clean container.
Keep the container covered to maintain modest moisture. Check each day and add water a drop at a time to the filter paper if necessary. The top of the egg will look dark before the larva is ready to emerge. Be sure to have a fresh milkweed leaf in the container for the new larva, if its old leaf is dry.
Once the larvae emerge, they will need fresh milkweed leaves. They won't eat any other plants, although they do eat many different species, or kinds, of milkweed. If the original plant is still fresh, it is easiest to just leave the larvae on this for a few days. They rarely crawl far during this time, and do not need to be put in a container until they are about four days old.
If you are keeping larvae in individual containers, be sure to replace leaves when they turn dry, every one to two days. Leaves will keep longer if the stem is wrapped in a moist paper towel and then wrapped in tin foil or plastic wrap. Containers should be emptied of frass larva waste every one to two days. For more information on finding and growing milkweed, see our Milkweed Guide.
If kept in a closed plastic bag in the refrigerator, milkweed will stay fresh for several days. You will need to save a lot of leaves to keep rearing larvae, but some teachers have reared continuous generations of Monarchs using this method.
Larvae can be handled safely with fingers after they are about three to four days old, but it is best to handle them as little as possible until they are over an inch long.
If necessary, a moistened artist brush can be used to transfer younger larvae without hurting them. Larvae of any size should not be handled when they are molting.
They are getting ready to molt when they remain very still, often on the side or top of their container, and when you can see their black head capsule about to come off. Just after they have molted, their tentacles will look droopy, and you may see the old skin behind the larva. They will usually eat this skin! As larvae grow, so will their appetites. Be sure to check their leaf supply regularly.
If you started with a small container, you will need to move the larvae to a larger one for adequate food supply and with enough room for the adult butterflies to emerge from the chrysalis. This should be done during the fourth instar, when the larvae are about an inch long. Be sure the upper surface is flat for easy attachment for pupating. Many types of containers can be used; clear or screen sides make it easier for students to see the Monarchs. Examples of good rearing containers include jars or cups with lids with holes, or covered with netting held on with a rubber-band.
