Studies on social behavior and social structure of six Australian species of the genus Ropalidia were made during two years (1993 and 1994) with cooperation of Australian entomologists. Observations of marked females of Ropalidia revolutionalis and R.sp.nr.Variegata showed that their intracolony dominance relations were mild in pre-emergence stage but severe in post-emergence stage A swarm-founding, primitively eusocial species, R.mackaynsis constructed its nest in open space while the nest had no envelope. This is different from another swarm-founding, primitively eusocial species, R.socialistica, which produced nests in cavities.Contrary to other Australian primitively eusocial Ropalidia, R.gregaria spilocephala females founed their nests frequently by haplometrosis (single-female foundation).It was found that a highly eusocial species R.romandi cabeti founded their nest by swarming, and the swarm first constructed several combs and then constructed envelope. This is the first detailed record of the initial stage of nest foundation in swarm-founders.Many adult specimens were taken from many nests of a primitively eusocial, swarm founding species R.socialistica, and a highly eusocial swarm-founder, R.romandi cabeti. These were immediately frozen for future analysis with electrophoresis and DNA-finger printing technique, to estimate the intracolony relatedness.Comparative studies on social behavior, social structure and number of effective egg-layrs indicated that the genus Ropalidia, a large genus including 136 species, has three majour groups, individually-founding, primitively eusocial-species (e.g.R.revolutionalis), swarm founding, primitively eusocial species (e.g.R.mackaynsis) and swarm-founding, highly eusocial, multiqueen species, Ropalidia romandi. The second group was suggested to be a link between facultatively polygynous, primitively eusocial species as R.revolutionalis and R.gregaria and multiqueen species as R.romandi.

1993年和1994年，在澳大利亚昆虫学家的合作下，对六种澳大利亚卷蛾的社会行为和社会结构进行了研究。对革命圆粉蝶（Ropalidia revolutionalis）和杂色圆粉蝶（R.sp.nr.variegata）标记雌虫的观察表明，它们的群体内优势关系在羽化前为轻度，羽化后为重度。这与另一种群居的、具有明显的真社会性的物种R.socialistica在洞穴中筑巢不同，与澳大利亚其他具有明显的真社会性的Ropalidia不同，R.gregaria spilocephala的雌鸟经常通过单雌筑巢（单雌筑巢）来筑巢，而一种具有高度真社会性的物种R.romandi cabeti则是通过群居来筑巢的，它们首先建造多个巢梳，然后再建造巢被。这是首次详细记录了蜂群建立者建立巢的初始阶段。许多成年标本取自一个具有明显的真社会性的蜂群建立物种R.socialistica和一个具有高度真社会性的蜂群建立物种R.romandi cabeti的许多巢。通过对Ropalidia的社会行为、社会结构和有效产卵量的比较研究表明，Ropalidia属是一个包括136种的大属，其主要类群有三个：个体形成的类群、连续性的真社会种类群（例如R.revolutionalis）、集群建立的、完全真社会性的物种（例如R.mackaynsis）和集群建立的、高度真社会性的、多女王的物种Ropalidia romandi。第二组被认为是一夫多妻制，revolutionalis和R.gregaria和多女王物种之间的联系。
