Yuccas have a very specialized, mutualistic pollination system; being pollinated by yucca moths (family Prodoxidae); the insect transfers the pollen from the stamens of one plant to the stigma of another, and at the same time lays an egg in the flower; the moth larva then feeds on some of the developing seeds, always leaving enough seed to ...
Yucca filamentosa, [1] Adam's needle and thread, [2] is a species of flowering plant in the family Asparagaceae [3] native to the southeastern United States. Growing to 3 metres (10 feet) tall, it is an evergreen shrub valued in horticulture.
Another study takes a look at coevolution as a primary driver of change and diversification in the yucca moth and the Joshua tree, more commonly known as the yucca palm. The researchers tested this hypothesis by setting up a differential selection of two species of yucca moths and two corresponding species of yucca palms which they pollinate.
Hesperoyucca whipplei (syn. Yucca whipplei), the chaparral yucca, [2] our Lord's candle, [2] Spanish bayonet, [3] Quixote yucca [2] or foothill yucca, [4] is a species of flowering plant closely related to, and formerly usually included in, the genus Yucca. It is native to southwest communities of North America.
Yucca baccata is recognized by having leaves 50–76 cm (20–30 in) long [4] with a blue-green color, and short or nonexistent trunks. It flowers in the spring, starting in April to July depending on locality (altitude), and the flowers range from 5 to 13 cm (2 to 5 in) long, in six segments, [7] white to cream-coloured with purple shades.
The yucca, Yucca whipplei, is pollinated exclusively by Tegeticula maculata, a yucca moth that depends on the yucca for survival. [15] The moth eats the seeds of the plant, while gathering pollen. The pollen has evolved to become very sticky, and remains on the mouth parts when the moth moves to the next flower.
Yucca flaccida, commonly called Adam's needle [4] or weak-leaf yucca, [5] is a species of flowering plant in the asparagus family (Asparagaceae). It is native to south-central and southeastern North America, from the lower Great Plains eastward to the Atlantic seaboard in Virginia , south through Florida and the Gulf states. [ 6 ]
Tegeticula is a genus of moths of the family Prodoxidae, one of three genera known as yucca moths; they are mutualistic pollinators of various Yucca and Hesperoyucca species. Species [ edit ]
