Coccinellidae

Coccinellidae is a widespread family of small beetles ranging in size from 0.8 to 18 mm (0.03 to 0.71 inches).The family is commonly known as ladybugs in North America, and ladybirds in Britain and other parts of the English-speaking world. Entomologists prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs The majority of coccinellid species are generally considered useful insects, because many species prey on  herbivorous homopterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies in order to ensure their larvae have an immediate food source. However, some species do have unwelcome effects; among these, the most prominent are of the subfamily Epilachninae (which includes the Mexican bean beetle), which are herbivorous themselves. Usually, epilachnines are only minor agricultural pests, eating the leaves of grain, potatoes, beans, and v...

Gardenia

Gardenia is a genus of flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, Asia, Madagascar and Pacific Islands The genus was named by Carl Linnaeus and John Ellis after Dr. Alexander Garden (1730–1791), a Scottish-born American naturalist. They are evergreen shrubs and small trees growing to 1–15 metres (3.3–49.2 ft) tall. The leaves are opposite or in whorls of three or four, 5–50 centimetres (2.0–19.7 in) long and 3–25 centimetres (1.2–9.8 in) broad, dark green and glossy with a leathery texture. The flowers are solitary or in small clusters, white, or pale yellow, with a tubular-based corolla with 5–12 lobes (petals) from 5 to 12 centimetres (2.0 to 4.7 in) diameter. Flowering is from about mid-spring to mid-summer, and many species are strongly scented

Argania

Argania (Berber: ⴰⵔⴳⴰⵏ Argan) is a genus of flowering plants containing the sole species Argania spinosa, known as argan, a tree endemic to the calcareous semidesert Sous valley of southwestern Morocco[3] and to the region of Tindouf in southwestern Algeria[4][5]. Argan trees grow to 8–10 m (26–33 ft) high and live up to approximately 200 years. They are thorny, with gnarled trunks and wide spreading crown. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground. The leaves are small, 2–4 cm (0.79–1.57 in) long, and oval with a rounded apex. The flowers are small, with five pale yellow-green petals; flowering is in April. The fruit is 2–4 cm (0.79–1.57 in) long and 1.5–3 cm (0.59–1.18 in) broad, with a thick, bitter peel surrounding a sweet-smelling but unpleasantly flavored layer of pulpy pericarp. This surrounds the very hard nut, which contains one (occasionally two or three) small, oil-rich seeds. The fruit takes over a year to mat...
