Opuntia fragilis

Opuntia fragilis, known by the common names brittle pricklypear and little prickly pear, is a prickly pear cactus native to much of western North America as well as some eastern states such as Illinois, Iowa, Wisconsin and Michigan. It occurs in several Canadian provinces. It is known from farther north than any other cactus,[1] occurring at as far as 56°N latitude in British Columbia.[2] There is an isolated and possibly genetically unique population in Eastern Ontario known as the "Kaladar population".[3]

Brittle pricklypear is a small decumbent cactus that grows to a maximum height of 10 cm (3.9 in).[4] Both the common and scientific names refer to the easily detached stem segments. This is known to be a means of plant dispersal.[4]

Opuntia fragilis is a small, prostrate plant, rarely more than 10 cm (4 in) high: joints tumid, fragile, easily detached, oval, elliptical, or subglobose, 3–5 cm (1–2 in) long and nearly as thick as broad, bright green: areoles 0.6–1.3 cm (1412 in) apart, with whitish wool and a few white to yellow bristles, which are much longer and more abundant on older joints; spines 1–4, occasionally a few small additional ones, weak, dark brown, the upper one usually longer and stronger than the others, rarely 2.5 cm (1 in) in length: flowers greenish yellow, 2.5–3.2 cm (1–1 14 in) wide: fruit ovate to subglobose. with few spines or bristles, mostly sterile, 2.5 cm (1 in) or less long; seeds few and large. Rocky Mountain region from Canada to New Mexico.[5]

The forewings have a row of dark spots near the tip with one spot between each pair of veins and a distinct (but often weak) double zigzag cross-band, a distinct black discal spot and a weak, dark angled cross-band near the wing base. The hind wings are broad and white, mostly with grayish margins.

There is one generation per year.

The larvae feed on Opuntia species, including Opuntia fragilis, Opuntia macrorhiza and Opuntia polyacantha. Pupation takes place in the silk cases.

Opuntia, commonly called prickly pear, is a genus in the cactus family, Cactaceae. Prickly pears are also known as tuna (fruit), sabra, nopal (paddle, plural nopales) from the Nahuatl word nōpalli for the pads, or nostle, from the Nahuatl word nōchtli for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia (O. ficus-indica).
