Paratrigona Subnuda
''Paratrigona subnuda'', commonly known as the jataí-da-terra ("ground jataí"), is a species of eusocial stingless bee in the family Apidae and tribe Meliponini. These social bees are prevalent in Neotropical moist forests, including Brazilian Atlantic and other South American forests. They inhabit spherical nests in moist underground environments with their forest habitats. Within their Neotropical habitats the ''P. subnuda'' is considered to be a very successful and common species of bee. ''P. subnuda''’s main source of food is pollen and nectar from a large variety of native Mesoamerican tropical plants. They have been extensively studied due to social conflicts arising from single mate behaviors and particular virgin behaviors. ''P. subnuda'' also exhibits the particular daily behavior in which they open the nest entrance at dawn and close the entrance at dusk when all their activities are done. Taxonomy and phylogeny ''P. subnuda'' belongs to the family Apidae, but far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetragonisca Angustula
''Tetragonisca angustula'' is a small eusocial stingless bee found in México, Central and South America. It is known by a variety of names in different regions (e.g.'' jataí, yatei, jaty, virginitas, angelitas inglesas, españolita, mariola, chipisas, virgencitas,'' and ''mariolitas''). A subspecies, ''Tetragonisca angustula fiebrigi'', occupies different areas in South America and has a slightly different coloration. ''T. angustula'' is a very small bee and builds unobtrusive nests, allowing it to thrive in urban areas. It also produces large amounts of honey, and is thus frequently kept in wooden hives by beekeepers. ''T. angustula'' hives are often overlooked, and since the bee lacks a stinger, it is not seen as a threat to humans. Many of their behaviors are concerned with colonizing a new nest and producing offspring, demonstrated by their swarming and nursing behaviors, however a special caste of ''T. angustula'' are soldiers who are slightly larger than the workers.

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...
