We currently have three monarch caterpillars in our butterfly house, with one finishing up the molting process.
Did you know that a caterpillar will grow its new skin before shedding the old? When it molts, or sheds its skin, the larger skin is then exposed allowing the caterpillsr to enter the next instar and continue eating.
A monarch catepillar just finished molting, shedding its skin, so it can continue eating and growing to the perfect size.
We have quite a busy butterfly house right now with monarch caterpillars of every size.
There are three sections of a caterpillars body, of course, with the first being the hard head, which includes its mouth on the lower side. The caterpillar has two jaws, which move from side to side, and includes either teeth, or blades, to cut, eat, through the leaves. On quite a few occasions, if you stop and listen closely, you can hear the caterpillars munching on the leaves.
The caterpillars found in the garden today are of various different sizes and species. I am sure there are more that we just did not find.
In order for a caterpillar to grow, it molts, which I read can take a day or two for the entire process to be completed. It’s fascinating to watch, if you ever have the opportunity to do so. The molting process takes place on several occasions, as the caterpillar has to shed its skin, so it can continue to eat and grow to the desired length. When a caterpillar begins to molt, it will create a silk pad, while making sure its prolegs are firmly attached. I find it interesting that the caterpillar will swallow air to enlarge itself, before its cuticle splits along the thorax, so it can wiggle out of the old skin.
This monarch caterpillar has entered into another instar, eating the remains of its old skin. I have seen the catepillar going through the molting process, but this is the first time I have seen it eat the remains. Nature sure is remarkable to watch.
