          Abstract

          Male Neotropical orchid bees (Euglossini) collect volatile chemicals from floral and non-floral sources and store then in specialized hind tibial structures. The ultimate causes of euglossine fragrance collection remain a mystery. Recent evidence suggests that odoriferous substances play a role in euglossine courtship and serve as indicator of male genetic quality. Males of Eulaema nigrita were observed robbing scents from the detached hind legs of a conspecific male E. nigrita in Belém, Brazil. The hind leg seemed to have been detached during fights between males, since one male was missing a hind leg where the observation was made. This behavior appears to be common among males of E. nigrita since more than one case was observed on the same day. The observation reported here shows that males of E. nigrita with tibiae filled with fragrances are attacked by conspecific males that attempt to steal it.

          Translated abstract

          Machos das abelhas das orquídeas (Euglossini) coletam substâncias voláteis de fontes florais e não florais e armazenam estas em estruturas especializadas nas tíbias posteriores. O motivo pelo qual estas substâncias são coletadas permanece um mistério. Evidências recentes sugerem que estas substâncias são utilizadas durante a corte e são indicadoras da qualidade genética dos machos. Neste estudo, machos de Eulaema nigrita foram registrados roubando substâncias de uma perna posterior arrancada de outro macho de E. nigrita em um parque de Belém (Brasil). A perna posterior parece ter sido arrancada durante lutas entre machos, já que no local de observação havia um macho sem uma perna posterior. Esse comportamento parece ser comum entre machos de E. nigrita, um vez que no mesmo dia de observação foram registrados dois grupos distintos de machos voando e lutando ao redor de uma perna posterior arrancada. A observação registrada neste estudo mostra que machos de E. nigrita, que apresentam pernas cheias de essências, são atacados por machos da mesma espécie que procuram roubar as fragrâncias armazenadas.
