The Edith's checkerspot subspecies mirror the changes in climate over long periods of time. Global warming is expected to eliminate the butterflies in the south throughout the upcoming years, where the season is becoming shorter and shorter.
In areas of the lowest latitude, about three-fourths of the populations have become extinct. This is in contrast to higher latitude areas in Canada where less than twenty percent have disappeared.
It has been found that population extinctions were four times as high along the southern boundaries Baja and Mexico than along the northern boundaries Canada. In addition, extinctions are nearly three times as high at lower elevations below 8, feet 2, m than at higher elevations from 8, to 12, feet 2,—3, m.
In agreement with global warming predictions, this extinction process has shifted the range of this butterfly both northward and upward in elevation since the s.
In the case of Euphydryas editha quino , habitat destruction is the major reason for its decline, although climate change problems also pose a threat. Quino checkerspot populations along the southernmost boundary in Mexico are at the greatest risk from continuing warming and drying climate trends.
Unfortunately, these are also the best remaining habitats with the lowest degree of threat from development. By contrast, most Quino habitat has been destroyed by development in the Los Angeles—San Diego corridor.
The case of the Quino checkerspot has resulted in the first habitat recovery plan to list climate change not only as a current threat, but also as a factor that should be considered in reserve design and recovery management. Some sedentary checkerspots remain at their original habitats despite the continuation of human interference, and have evolved adaptations to deal with these changes. In January , the subspecies Euphydryas editha quino and Euphydryas editha bayensis received federal protection under the Endangered Species Act.
Euphydryas editha bayensis has also been given the Nature Conservancy global rank of T1, which means that there are very few individuals remaining.
Edith's checkerspots lay their eggs on various plant species, sometimes resulting in the death of the host plant, which could be potentially economically important to humans. In addition, larvae, pupae, and adults are poisonous to vertebrates if ingested. A plus for humans involves pollination, because in order to obtain nectar, adult butterflies of the species sometimes pollinate various flowers in the area of their habitat.
This species is often better known by the constituent subspecies listed below. It is subject to change as the nomenclature is altered or new subspecies are found. Edith's checkerspot facts for kids Kids Encyclopedia Facts.
