Monarch caterpillar Monarch caterpillars (Danaus plexippus) go through 5 instars before emerging as adult common butterflies. Monarch caterpillar This caterpillar is green or gray in its first instar. The rest of its instars show distinct black, white, and yellow bands across the body which grow in size as the caterpillar grows. Caterpillars of this genus are commonly found on milkweed and they may become aggressive toward each other based on low food availability. These caterpillars finally move away from milkweed in the fifth instar when they stop feeding. They seek out a shelter pupating place. 2. Eastern Tiger Swallowtail caterpillar Eastern Tiger Swallowtail caterpillar Some caterpillars drastically change colors before pupating and becoming adult butterflies. This is also the case with the color-changing Eastern Tiger Swallowtail (Papilio glaucus). These caterpillars have a brown color in the first instars which changes to green coloring in late instars. Eastern Tige...

Some of the most common caterpillars that stand out are yellow. They represent the life stage of moths or butterflies and can be found in various regions of the world, including North America. Seen in one or multiple broods per year, these caterpillars might appear poisonous and they tend to have fewer numbers of natural predators compared to other species. Yellow caterpillars might be yellow through all of their life stages or they might turn yellow either in the first or in the last instars. Caterpillars often have black or red contrasting colors as purely-yellow species are rare.

The poisonous or toxic nature of yellow caterpillars is up for debate. Even species that may cause skin reactions don’t cause these reactions in all humans. Yellow Tussock moth caterpillars are among the most common species to cause welts. This is a type of skin urticaria. Rashes of this type don’t require medical attention but they might be more intense in children on seniors. It’s the hairs of these caterpillars that might cause skin rashes in case of direct contact. Even hairs that have fallen off the caterpillar can cause similar reactions. Most types of yellow caterpillars aren’t poisonous or dangerous to host plants or trees. These types of caterpillars might become a problem when multiplying rapidly in high numbers. This might be the case in late summer f...

Find out about monarch caterpillar stages with pictures and facts. The monarch butterfly, like all butterflies, goes through 4 main developmental stages: egg; larva (caterpillar); pupa (chrysalis); and imago (adult butterfly). What many people don’t know is that, as a caterpillar, the monarch also goes through several stages of development. On this page we’ll find out about the 5 monarch ‘instars’; the stages a monarch caterpillar goes through before pupation… Monarch Caterpillar Stages Most people know that the life cycle of the monarch butterfly has four distinct stages: egg, caterpillar, chrysalis and imago (the adult butterfly). The Life Cycle Of The Monarch Butterfly. Click photo to go to our • You can find out about each of these stages on this page: What many people don’t know is that the monarch caterpillar itself has five stages of development. At the end of each stage the caterpillar molts (moults in British English). By shedding its skin the caterpillar is able to continue growing; each successive stage is larger and heavier than the last. The caterpillar also undergoes slight changes in appearance at each stage. By the end of the fifth stage of the monarch caterpillar’s development, it will have reached the size and weight required for pupation (i.e. turning into a chrysalis). Before its fifth and final molt, the caterpillar attaches itself to the underside of a leaf or other suitable surface. The final molt, which is performed while the caterpillar is hanging ...
