In 3 days ~20% in a week ~40%
Partamona helleri, the Heller's stingless bee, is a species of stingless bee from Brazil. It is an aggressive species of bee, when threatened it coils around the victim's hair and fur, in addition to nibbling the skin with its mandibles.
It occurs in the neotropical region of Brazil, from the south region to the northeast region in the states of Bahia, Espírito Santo, Minas Gerais, Paraná, Paraíba, Pernambuco, Rio de Janeiro, Santa Catarina, Sergipe and São Paulo.
Partamona helleri constructs the entrance to its nest in the shape of a large frog's mouth, made of clay with propolis, because of this it is also known as the "toad's mouth bee". The wide outer entrance of the funnel-shaped nest is correlated with the defense of the colony, because it facilitates forager traffic while the narrow inner entrance requires only a few guards to defend.
The construction process involves the use of wax, pure or mixed plant resins, and, in some cases, soil mixed with resins. The entrance structures are distinct and elaborate, varying among Partamona species. The chosen substrate and nest architecture are adapted to provide protection against predators... Wikipedia →
