The moth or butterfly will remain in this stage until they emerge as an adult. Although some moth caterpillars burrow into the soil to pupate, generally they will pupate inside a cocoon. A moth caterpillar fashions its silky cocoon using a glue-like substance which they spin around themselves. Moth caterpillars have special glands which start producing this sticky substance in preparation for its metamorphosis. Once inside the cocoon, the moth will pupate.
Silk worm caterpillars in particular rely only on their own silk, knitting a shell around themselves. Other moth caterpillars use parts of leaves to create a patchwork cocoon. A butterfly pupa is also called a chrysalis, and they can be quite beautiful, with interesting patterning or shiny gold colouration.
Instead, they may be using the light for navigation. There is not one clear answer yet, but many think that moths mistake artificial lights for the Moon and are drawn to them for this reason.
However, they may stay bouncing around your lampshade because they become disorientated by the light once they are close. So, are moths drawn to a flame or lightbulb doomed to keep dying? A group of researchers tested the impact of light pollution on moths in , and found city moths were less likely to display this flight-to-light behaviour , indicating that they are evolving to avoid these light traps.
Moths : Have simple thread-like or 'feathery' antenna without a club Butterflies and Skippers : Have a thickened club or hook on the tip of the antenna, never 'feathery' Exceptions : Several families of moths have antenna with clubs, most notably the Castniidae Sun Moths. Many butterflies and skippers are dark brown with few markings. Moths : Wings are linked together with a bristle-like structure called a frenulum Butterflies and Skippers : Wings are not linked — no frenulum Exceptions : Australia has the only skipper in the world with a frenulum, the Regent Skipper Euschemon rafflesia Hesperiidae.
Also, many moths do not have a frenulum. Resting posture. Moths : Hold wings flat when resting Butterflies and Skippers : Hold wings together above body when resting Exceptions : Many moths, including geometrid moths hold their wings up in a butterfly-like fashion when resting.
Butterflies in the lycaenid subfamily Riodininae, and skippers in the subfamily Pyrginae hold their wings flat when resting. Moths : Forelegs fully developed Butterflies and Skippers : Forelegs reduced, missing terminal end segments Exceptions : Only some butterflies have reduced forelegs. Most skippers have normal forelegs. Science Bob welcome to sciencebob.
A moth and a butterfly sure can look alike, and they both belong to the same insect family Lepidoptera but there are a few differences to look for so that you can tell them apart: Butterflies usually rest with their wings closed, while moths rest with their wings open. Butterflies have long, thin antenna, while moths have shorter feathery antennas.
Butterflies, on the other hand, form chrysalises, which are hard, smooth and silkless. Physical differences abound. Butterfly antennae are thin with club-shaped tips, compared with the feathery or comb-like antennae of moths. Moths are stout and fuzzy; butterflies are slender and smooth.
