ABSTRACT This study explores egg eclosion and larval biology of orchid bees (Apidae: Euglossini) in light of existing knowledge from studies dealing with a group of tribes within the Apidae referred to as corbiculate bees. It reports that Eulaema (Apeulaema) polychroma (Mocsáry) has five larval instars, and its first instar exists only briefly in that with the help of a band of spicules along both of its sides its exoskeleton is shed with the remnants of the chorion. Mature larvae of euglossines exhibit two anatomical features that are not characteristic of other corbiculates, namely the elongate, tapering area of the prothorax immediately behind the head and the small size of the cranium. These features are suggested to be accommodations allowing the development of the extremely long labiomaxillary region of the pupa, which in turn accounts for the lengthy mouthparts of the adult. Descriptions of the egg and mature larva of Euglossa (Euglossa) hemichlora Cockerell are appended as well as referenced in the text.

浅色蜜蜂的卵羽化和幼虫发育

摘要 本研究根据对 Apidae 中被称为球状蜜蜂的一组部落的研究的现有知识，探讨了兰花蜜蜂（Apidae：Euglossini）的卵羽化和幼虫生物学。据报道，Eulaema (Apeulaema) polychroma (Mocsáry) 有五个幼虫龄，它的第一个龄期只存在很短的时间，因为它的外骨骼在其两侧的针刺带的帮助下与绒毛膜的残余物一起脱落。euglossines 的成熟幼虫表现出两个解剖学特征，这两个解剖学特征不是其他小圆虫的特征，即紧邻头部后面的前胸的细长锥形区域和小尺寸的颅骨。这些特征被认为是允许蛹极长的唇上颌区域发育的调节，这反过来解释了成年人的长口器。Euglossa (Euglossa) hemichlora Cockerell 的卵和成熟幼虫的描述附在文中并引用。
