The Baltimore checkerspot (Euphydryas phaeton) is a North American butterfly of the family Nymphalidae. It has been the official state insect of the U.S. State of Maryland since 1973. [2] The Baltimore checkerspot was named for the first Lord Baltimore due to its similarity of colors in the family crest. [3] Despite the species status as Maryland state insect, the population in Maryland has faced significant decline and is currently listed by the Maryland Department of Natural Resources as "rare, threatened, and endangered" animal list.

Life cycle

During its period of growth, the checkerspot butterfly will search for a host plant for nourishment. Its native larval host is the white turtle head ( Chelone glabra ), but it has also to some extent made use of the introduced lawn weed English plantain ( Plantago lanceolata ) [5] and other plants. [6]

Unlike most butterflies and moths, which overwinter as eggs, pupae, or sometimes adults, the Baltimore checkerspot overwinters as larvae. In late summer (sometime in July through September depending on latitude, weather, and other factors) the larvae spin a pre-hibernation web on a plant, stop feeding, and remain in the web. Several months later they leave this web and enter the litter (dead grass and leaves and so on) on the ground, where they spend the winter. [7]

<i>Castilleja</i> Genus of flowering plants belonging to the broomrape family

Castilleja, commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family Orobanchaceae. They are hemiparasitic on the roots of grasses and forbs. The generic name honors Spanish botanist Domingo Castillejo.

<span class="mw-page-title-main">Nymphalidae</span> Largest butterfly family

The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.

<span class="mw-page-title-main">Marsh fritillary</span> Species of butterfly

The marsh fritillary is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. The larvae are dependent on the host food plant Succisa pratensis not only for feeding but also for hibernation, because silken webs are formed on the host plant as the gregarious larvae enter hibernation. Females lay eggs in batches on the host plant and are, like other batch-layers, selective about the location of oviposition because offspring survivorship levels for batch-layers are more tied to location selection than they are for single-egg layers.

Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, most often bound to glucose.

The callippe silverspot butterfly is a federal endangered subspecies in the brush-footed butterfly family Nymphalidae. This is a subspecies. It is a member of the Heliconiinae, the subfamily known as longwings. The adult has a wingspan of just over two inches. The wings are eyecatching with a brown, tan, and black scalloped pattern on their surfaces and orange-brown with characteristic silver spots on the undersides. The wings and abdomen are hairy. The larvae are spiny, dark-colored caterpillars.

<i>Chelone glabra</i> Species of flowering plant

Chelone glabra, or white turtlehead, is a herbaceous species of plant native to North America. Its native range extends from Georgia to Newfoundland and Labrador and from Mississippi to Manitoba. Its common name comes from the appearance of its flower petals, which resemble the head of a tortoise. In fact, in Greek, chelone means "tortoise" and was the name of a nymph who refused to attend the wedding of Zeus and was turned into a turtle as punishment. Its natural habitat is wet areas, such as riparian forests and swamps.

<span class="mw-page-title-main">Variable checkerspot</span> Species of butterfly

The variable checkerspot or Chalcedon checkerspot is a butterfly in the family Nymphalidae. It is found in western North America, where its range stretches from Alaska in the north to Baja California in the south and extends east through the Rocky Mountains into Colorado, Montana, New Mexico and Wyoming. The butterfly is usually brown or black with extensive white and yellow checkering and some red coloration on the dorsal wing. Adult wingspan is 3.2–5.7 cm (1.3–2.2 in). Adult butterflies feed on nectar from flowers while larvae feed on a variety of plants including snowberry (Symphoricarpos), paintbrush (Castilleja), Buddleja, Diplacus aurantiacus and Scrophularia californica.

<span class="mw-page-title-main">Edith's checkerspot</span> Species of butterfly

Edith's checkerspot is a species of butterfly in the family Nymphalidae. It is a resident species of western North America and among the subspecies, entomologists have long been intrigued by their many phenotypic variations in coloration, wing length, and overall body size. Most populations are monophagous and rely on plants including Plantago erecta and Orthocarpus densiflorus as their host species in developing from eggs through to larvae, pupae, and mature butterflies. Males exhibit polygyny whereas females rarely mate more than once. Males devote most of their attention to mate acquisition, and such mate locating strategies such as hilltopping behavior have developed. Climate change and habitat destruction have impacted certain subspecies. Three subspecies in particular, Euphydryas editha quino, Euphydryas editha bayensis and Euphydryas editha taylori, are currently under protection via the Endangered Species Act.
