Stelis (bee)
''Stelis'' is a genus of kleptoparasitic bees in the family Megachilidae Megachilidae is a cosmopolitan family of mostly solitary bees. Both that their pollen-carrying structure (called a ''scopa'') is restricted to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other b .... There are at least 100 described species in ''Stelis''. Description One study of the species '' Stelis ater'' found they differed a bit from other thieving bees by being hospicidal (host-killing) at all larval stages, and neither it nor its host larva move much, so it is simply a matter of chance when its growth brings it into contact with the host rather than with just the provisions. This is in contrast to other kleptoparasitic bees which usually have their more mobile first instar larva kill the host larva.

Kleptoparasite
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megachilidae
Megachilidae is a cosmopolitan family of mostly solitary bees. Both that their pollen-carrying structure (called a ''scopa'') is restricted to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families), and their typically elongated labrum is characteristic of this family. C. D. Michener (2007) ''The Bees of the World'', 2nd Edition, pg. 122, Johns Hopkins University Press. Megachilid genera are most commonly known as mason bees and leafcutter bees, reflecting the materials from which they build their nest cells (soil or leaves, respectively); a few collect plant or animal hairs and fibers, and are called carder bees, while others use plant resins in nest construction and are correspondingly called resin bees. All species feed on nectar and pollen, but a few are kleptoparasites (informally called "cuckoo bees"), feeding on pollen collected by other megachilid bees. Parasitic species do not possess scopae.

Stelis Lateralis, F, Side, New York, Kings County 2013-03-05-15
''Stelis'', or leach orchids, is a large genus of orchids, with perhaps 500 species. The generic name ''Stelis'' is the Greek word for 'mistletoe', referring to the epiphytic habit of these species. These mainly epiphytic (rarely lithophytic) plants are widely distributed throughout much of South America, Central America, Mexico, the West Indies and Florida. Many of the older species were named by Lindley, Ruiz & Pavon and Reichenbach, while many of the recent species were named by Carlyle A. Luer. An orchid of the genus ''Stelis'' was probably the first American orchid ever to be brought to Europe. An herbarium specimen was depicted in 1591 in Tabernaemontanus' herbal book. Description A single oblanceolate leaf develops from narrow, leathery outgrowths from a creeping stem. Most species grow long, dense racemes of small to minute flower in diverse shades of white. Other colors are rare. These flowers are photosensitive, only opening in the sunlight. Some close completely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
