BUTTERFLIES & MOTHS

[photo, Female (dark morph) Eastern Tiger Swallowtail (Papilio glaucus) butterfly, Monkton, Maryland] There are over 150 species of butterflies and skippers throughout Maryland. Butterflies, depending on the species, pollinate plants or eat harmful insects, and their presence (or lack thereof) is an indicator of the health of the surrounding environment. Many species are found in a variety of habitats, but some stay within a specific area, close to their food source.

[photo, Black Swallowtail (Papilio polyxenes) caterpillar, Monkton, Maryland] Butterflies go through three stages before they reach the final adult stage: egg, caterpillar or larvae, and pupa or chrysalis. Adult butterflies have four finely-scaled wings, scaled bodies, six legs, two compound eyes, and a proboscis or mouthpart. They are diurnal and can live up to a year, depending on the species, but most live much shorter lives.

Butterflies (Rhopalocera). Butterflies belong to the suborder Rhopalocera. They can be further divided into three groups or superfamilies: true butterflies, skippers, and moth-butterflies.

They generally are dull in color, usually grey or brown, but can have wave-like or swirl patterns on their wings to serve as camouflage. They have stout, hairy-like bodies, broad wings with large scales, feathery, unclubbed antennae, and a proboscis. A frenulum, or a line of tissue connects their wings. Unlike butterflies, most moth caterpillars form a silk cocoon instead of a chysalis. Moths are generally nocturnal.

The common belief that moths are furry, while butterflies are not, is scientifically inaccurate. Although individual species may be called either butterfly or moth, the two are so closely related that division even at the family level is not considered sound.

[photo, Spicebush Swallowtail (Papilio troilus) butterfly on Zinnea, Glen Burnie, Maryland] What distinguishes Lepidoptera are their comparatively large wings and antennae. While a small number of species possess crossvein wings, most have large membranous wings of various colors and patterns. Although the colors and patterns of butterflies are beautiful, they serve as camouflage or as a warning to predators.

Their bodies are covered with thick coats of bristles or setae. Woolly bears eat grass, herbs, and plant leaves. They will roll into a defensive ball if disturbed.

MARYLAND BUTTERFLIES & MOTHS

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
While flying, the colors and patterns on a butterfly's dorsal (back) side, are readily visible; however, when resting, a butterfly usually folds its wings over its back, allowing the colors on the ventral (underside) side, to be displayed. A moth, on the other hand, will spread its wings to the sides, showing its back or dorsal side on top, while at rest.
