Euphydryas editha taylori, the Whulge checkerspot or Taylor's checkerspot, is a butterfly native to an area of the northwestern United States and Vancouver Island.

Contents

Description

Taylor's checkerspot is the darkest subspecies of the genus Euphydryas . It is a subspecies of Edith's checkerspot. This butterfly has a wingspan of less than 2.25 inches (57 mm). It gets its name from the checkered color pattern on its wings that consist of black, orange and white coloring. [1] Taylor's checkerspot once ranged from the Willamette Valley in Oregon to Vancouver Island in British Columbia.

Chemical ecology

Taylor's checkerspot larvae rely on complex multitrophic interactions for survival. The larvae feed upon certain plant species in the native Castilleja and exotic Plantago genera that produce defensive compounds called iridoid glycosides. [2] [3] Over time, the Taylor's checkerspot has developed a tolerance for these compounds, such that the larvae are able to consume the foliage of these plants and sequester the compounds in their own tissues. [2] [3] These compounds then confer chemical protection against bird predators to the larvae. [2] [3]

Conservation status

The Taylor's checkerspot butterfly is at extreme risk of going extinct. [1] It was listed as endangered under the U.S. Endangered Species Act in 2013. [4] In 2006, it was listed as state-endangered in Washington, where an active conservation program is underway. [5] In Oregon Taylor's checkerspot is on the Threatened and Endangered Species list, but receives no protection under state statute. Before its dramatic decline Taylor's checkerspot was documented at more than seventy sites, but is currently found only at ten sites in Washington and two in Oregon. [1] It is currently listed as endangered in Canada, owing to the recent discovery of populations on Denman Island. [6]

Threats

The biggest threat to its survival is the loss of prairie habitat due to contemporary settlement. More than 99% of the lowland prairies has been destroyed. The reason for this is that prairies are prime locations for agriculture as well as development of all types due to the lack of trees and flat topography. [7] Along with habitat loss the subspecies is impacted by pesticide use that makes their plight even worse. [8] Increased risk of harm due to drought is another major concern since they are now stuck on these patches of habitat with no chance to migrate to more suitable places.

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">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.

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.

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.

There are usually many stemlike inflorescences growing erect to a maximum height of around 15 cm (6 in). Atop the peduncle of the inflorescence is a dense cylindrical or somewhat conical spike of several tiny flowers and bracts. The spike is very woolly.
