      The blood of some butterfly species contains natural antifreeze agents -- glycerol and sorbitol -- which allow them to live in certain stages of their life cycle during subfreezing temperatures. During this period, their development comes to a standstill and vital functions are kept at bare minimum. What do butterflies eat? Most adult butterflies prefer sipping nectar from any flower they can access.The type of flower a butterfly visits depends on the length of the butterfly's tubelike tongue, called a proboscis. A butterfly's tongue functions much like a flexible straw, uncoiling when it's ready to sip sweet nectar from a flower. The tongue recoils back into position when not in use.Some species, such as red admirals and mourning cloaks, rarely visit flowers. Instead they seek out sap flows on trees, as well as pollen, fermenting fruit, bird droppings and dung. While adult butterflies will feed from a wide variety of nectar flowers, caterpillars typically have very specialized diets. For instance, plants in the mallow family are favored by the west coast lady and the common checkered-skipper caterpillars, while monarch caterpillars feed solely on milkweed.Most caterpillars dine on specific plants, usually on the leaves, though some species do eat seeds, seedpods or flowers. Why are butterfly wings so colorful? The rich patterns and vivid colors come from layers of thousands of tiny scales, most of which are produced by pigments. Each scale is composed of a single color. The scales protect the wings, and the overall color patterns protect the butterfly from predators. Second, they do not reproduce right after they emerge.In response to decreasing temperatures and shortening daylengths at the end of the summer, their reproductive organs remain in an immature state. Instead of mating and laying eggs, they spend their time drinking nectar and clustering together in nighttime roosts in preparation for their long journey south.This delayed maturity is called diapause. Most of the monarchs will remain in this condition until the following spring, when they begin to mate in the overwintering colonies. During September, October, and early November, migratory adults fly to overwintering sites in central Mexico, where they remain from November to March. In March, they begin to journey north, laying the eggs that will become the new Generation 1 along the way.Annual Life Cycle. Generation 1 Monarchs in Generation 1 are the offspring of the monarchs that overwinter. Life Cycle Summary The first monarch generation of the year begins when females that have spent the winter in Mexico lay eggs in northern Mexico and the southern U.Generation 2 Monarchs in Generation 2 are the grandchildren of the overwintering monarchs. Life Cycle Summary Generation 2 larvae are widely distributed throughout the eastern United States, first beginning to appear in the south in early May, and in the north in mid to late May. Life Cycle Summary Generations 3 and 4 monarch eggs are laid throughout the northern part of their range in July and August. Similarly, should we allow monarch eggs that were laid way too late to become adults to survive?Mother nature would have removed these. The Darwinian logic makes sense. Ideally, you would have them in a place that mimics natural light cycles—no harsh fluorescent lights. Commercial butterfly breeder Connie Hodson of Flutterby Gardens in Florida suggests using sponges—scrubbers, actually—soaked in grape- or punch-flavored Gatorade laid out in shallow dishes inside a pop-up butterfly cage.Hodsdon has raised tens of thousands of butterflies and has moody weather in Tampa Bay similar to ours in South Texas. At that point, they will extend their long proboscis and slurp some fuel to power their flight. Photo by Monika Maeckle.

I had 2 chrysalis still hanging the end of October. One finally opened and flew away.The other is still hanging and presumed not viable. I just left them alone. Nature will take care of it. I have 40 caterpillars Monarch with this extreme drop in temps, here in Montgomery, Alabama. I decided to dig up my few plants and bring then inside until they can hopefully have a chance when it warms up, and just pray there are enough milk weed leaves to sustain them until they cocoon.I know the smaller ones will not survive, but many large enough to do their thing. Hoping for the best. Praying for the best outcome, long live our Monarchs. I lucked out the last two years here in Milwaukee, WI!I had 1 late Monarch last year and two this year eclose right before cold fronts that would have been the end of them. They use a combination of visual and chemical cues to find milkweed. Once they land on a plant, they use sensory organs on their feet and heads to tell them if it is a milkweed, and probably the quality of the milkweed. Females will wait a long time to find milkweed. Sometimes in our cages we keep mated females without milkweed, and VERY rarely, we will find a few eggs on other plants or the sponges we use to feed the females.The caterpillars then die. We have done studies here at the University of Minnesota of females that were overwintering in Mexico. The studies have shown that having milkweed around actually speeds up egg development. In some butterfly species you can see these testes from the outside, but not monarchs. At no time between egg fertilization and death do all body parts break down. Many of the features unique to the adult—such as the wings, eyes, internal reproductive organs, and long antennae—are actually present as tiny clusters of cells even in the egg.These cell clusters grow and differentiate throughout the larval stage. During the pupa stage, they rearrange and develop further. For example, the adult compound eye forms from cells that were behind the larval eyes.Some body parts, especially muscles, degenerate at the end of the larval stage and are replaced by new muscles that allow the new kinds of movements associated with the adult stage. Larvae move very differently than adults, and thus most of their muscles are completely broken down by enzymes early during the pupa stage. These broken down muscles do form a liquid within the developing pupa.I try to video the whole cycle. I notice that, during the first week of a chrysalid, it looks like it is empty, except at the top. This is why I have always wondered if the skin, itself, of the chrysalid, plays a significant role in the formation of the wings and other organs. I think this because of the immediate visible pattern of the wings, etc. It appears that the wings grow from the skin inward.Is there a lining against the inner skin that begins to form the wings? A: The skin or exoskeleton of the chrysalis is shed, in a way similar to that in which the exoskeleton of each of the previous larval instars is shed.While it may appear that the wings and other organs grow from the skin inward, they are actually present in the larva, and grow continuously in the last larval instar.
