Caterpillars feed on leaves throughout the summer. The adult moths donТt eat at all. The cecropia caterpillar eats the leaves of many trees and shrubs, including ash, birch, box elder, alder, elm, maple, poplar, wild cherry, plum, willow, apple, and lilac. The cecropia moth does not eat. It's only purpose it to mate. It only lives for a few weeks.
Cecropia moths are beautiful silk moths with reddish bodies and black to brown wings surrounded by bands of white, red, and tan. With a wingspan of five to seven inches 13 to 18 centimetersthe cecropia moth is the largest moth found in North America.
These nocturnal moths are found in hardwood forests east of the Rocky Mountains in the United States and Canada. They are attracted to street and porch lights, which is where most people encounter them. In what do cecropia moth caterpillars eat to find a mate, male cecropia moths must have extraordinary senses.
A female moth produces natural chemicals called pheromones, which the male can detect from over a mile away. When the caterpillars hatch, they are black in color.
As they go through successive molts, they increase in size and change color from black to yellow to green. At the end of the summer, the five-inch-long caterpillar seals itself into a cocoon and emerges in the spring as a moth. The sole purpose of the adult stage is to mate and lay eggs.

Food for Caterpillars
Caring for Cecropia Moth Caterpillars Х Feed the same kind of leaves on which the caterpillars have been started. Caterpillars may die if they are fed a new kind of leaves. Х Add fresh leaves each day. Х Clean out the frass (Excrement). Х When the caterpillars grow larger be sure to separate them otherwise they will start to eat each wooustoday.com Size: KB. Caterpillar Food The caterpillars will need to start eating right away. They all eat plant leaves, but each species is particular about the kinds of leaves it will eat. Here are lists of food plants IТve seen listed for each species. (The first plant on each list Ц in bold- is what I fed my caterpillars.). Sep 10, †Ј They also love to feed on the flowers and leaves. Cocoons hatch in the end of May and the beginning of June. Cecropia moths are born without mandibles, so your adult mothТs sole purpose in life is to hatch, mate, lay eggs and typically die within 1Ц2 .
I raised Cecropia, Polyphemus and Promethea moths for a few years and these are instructions based on my experiences. The timing of what I did works for eastern Minnesota and west-central Wisconsin Ч in other parts of the country the timing will be different.
These are the methods that worked best for me, but you may find other methods that work better for you. Lifecycle These four moth species all emerge from their cocoons in late May or June.
The caterpillars hatch within a week or so after the eggs were laid. The caterpillars eat and grow all summer, and make their cocoons in August or September. They go through the pupa stage Ч the change from a caterpillar to an adult Ч inside their cocoons. They over winter in their cocoons, and the adults emerge the following spring. Luna and Polyphemus moths sometimes go through two generations in one year.
Some adults will emerge from those early cocoons in mid-summer, and they will go through another cycle and make cocoons in the fall which will overwinter. Eggs to Caterpillars Eggs are laid on whatever happens to be available when the female has finished mating. Keep watch on the eggs, and a week or two after they were laid, the caterpillars will start to hatch.
At first the caterpillars are tiny Ч less than half an inch long Ч and black with black spines. Caterpillars will go through five instars before making their cocoon.
The skin of each instar is a little different. Here are some later Cecropia instars. Here are examples of caterpillars of the other species remember Ч each instar looks a little different. Caterpillar Food The caterpillars will need to start eating right away. They all eat plant leaves, but each species is particular about the kinds of leaves it will eat. The first plant on each list Ч in bold- is what I fed my caterpillars.

Luna : black walnut , birch, persimmon, sweet gum, hickory, pecan, sumac Bugguide. Once the caterpillars start eating, they like to keep eating the same thing, so choose a kind of leaf that you can get plenty of. If you are starting with eggs, or small caterpillars, the cage needs to be very secure Ч with no holes or cracks.
When the caterpillars first hatch they go looking for something to eat. If they find a crack in the cage before they find the food, they may escape. The cage for the eggs and tiny caterpillars should have a little air circulation, but not so much that they dry out.
A glass jar or plastic box with a screen stretched across the top works well. If they are going to be outside, the cage should keep them safe from predators Ч birds, mice, cats, insects and spiders. The screening material should be very fine mesh Ч window screening or smaller Ч to keep out insect predators.
I keep my cages on a screened porch. The two layers of screening Ч one on the porch and one on the cage Ч seems to completely exclude predators. If the cage is made of glass, be sure the top lets in air, and keep it out of the sun. The sun heats up the air inside and will cook the caterpillars. Plastic boxes covered with screening or fabric.
This cage is especially good for small caterpillars. I cut out the center of the lid, lay a piece of gauzy fabric over the box, and snap the lid edge on over the fabric. This cage is better for older caterpillars. It has small cracks between the top and bottom and the sides, so if the caterpillars are too small, they can escape. Sometimes, if they start to run out of fresh leaves, I find caterpillars crawling around on the outside of the cage.
But large cages like this Ч made with 20 inch saucers and 2 feet high Ч will hold 10 or 12 large caterpillars. Materials: Plastic coated fencing that comes in 2 foot high rolls Plastic screening also comes in a roll 2 large 20 inches in diameter plastic saucers the kind that are used under large plastic plant pots Needle and thread.
Instructions: Unroll enough of the fencing to make a cylinder that exactly fits inside one of the plastic saucers. Cut and fasten the wire cylinder together.
Cut and sew a piece of plastic screening around the outside of the fencing. Use the two saucers as the top and the bottom of the cage. If the caterpillars are too crowded they may get sick. Feeding your caterpillars You need to find a way to offer the caterpillars fresh leaves but protect them from drowning.
Access to the water can be blocked with a crumpled piece of waxed paper or plastic wrap stuck between the stems. Or you can put the water in a plastic container with a plastic lid. Punch a few holes in the lid for the stems to go through. Be sure all the holes are filled Ч or cover unused holes with tape Ч the caterpillars will find any open holes.
Put fresh leaves in when the old leaves look wilted. If I check on them the next day, any caterpillars that I missed will have found their way onto the fresh food. When I move the caterpillars to the fresh food, I try not to touch them. They do better without much human contact. When the caterpillars are small, the frass will be small, but when they get larger, the frass will be larger and messier. I clean smaller caterpillar cages every 3 or 4 days.
Larger caterpillars need their cages cleaned every day or two. Cocoons In August or the beginning of September the caterpillars will be about as big as your thumb and ready to make their cocoons. The different species build different kinds of cocoons. Cecropias build their cocoons by attaching to branches or the side of their cage. They start by throwing out silk, like spider silk, all around themselves. Polyphemus and Luna caterpillars make their cocoons on the ground, or on the floor of their cage.
They usually incorporate dried leaves in with the cocoon. These are two Promethea cocoons. After the cocoons are finished and the weather is colder, they need to go through the cold of the winter. This outdoor stage is very important Ч they need to go through a winter because it keeps them on the same schedule as the moths in the wild.
When they hatch, there need to be other moths hatching so they have partners to mate with. If you keep them inside in your warm house, the adults will emerge in the middle of the winter. Cecropia and Promethea cocoons can be left outside in their cages. I put them in a plastic container with a lid, and add a small wadded up piece of paper towel moistened with a few drops of water.
Every 6 weeks I refresh the water on the towel. Otherwise your frost-free refrigerator will dry out the cocoons. The next spring the moths will emerge sometime between the middle of May and the middle of June. The warmer the weather, the earlier the moths will emerge.
When it gets close to the right time for them to emerge, check the cocoons every day to be sure not to miss them. The moths will usually emerge in the middle of the day, and spend the day pumping up and drying their wings. Here is a series of photos of a moth emerging. Now you have to know if you have a male or a female moth. Males have very large, feathery antennae. Female antennae are much thinner.
Here are some photos to help you see the difference. If you have a male, release it when it gets dark. If you let it go in the light, it will be visible to predators and it may get eaten. If you have a female, you have a choice Ч you can let it go to live its life in the wild, or you can keep it for another day and watch for a male to come to mate. The job of the adult moths is to mate and lay eggs.
The males scent these pheromones and fly to the females. Cecropias, Polyphemus and Lunas all mate at night.
Prometheas mate in the late afternoon. The mating pair will stay coupled for hours Ч often overnight. If you want to mate a female, you can put her in a cage with large enough holes to allow her to mate through the cage. Release the male as soon as it gets dark. You can either release the female then, or keep her for a while, until she lays some eggs in the cage, and then release her to lay the rest in the wild.
If you get them from a place with different environmental conditions, even if the species is native to your area, their timing or food preferences may be different and they may not survive. Or put on some bright outside lights at the end of May or June Ч or whenever the adults fly in your area Ч and see if one is attracted to your lights. Be sure to release her the next day so she can lay the rest of her eggs in the wild.
