Euphaea opaca Selys, 1853 is an endemic damselfly to China, but little is known about its biology and ecology. In this study, we investigated the life history and secondary production of E. opaca in a third order subtropical stream of Guangdong, China. Larvae were collected monthly from October 2010 to September 2011 using a Surber…
Submerged oviposition behaviour by female Euphaea decorata and E. subcostalis is reported. E. decorata descended to within 10 cm of the stream bottom and oviposited endophytically for a total of 59 min. An E. subcostalis female descended 3 cm to dead leaves at the stream bottom and stayed submerged for 20-25 s. Non-contact guarding by…
Litheuphaea ludwigi sp. n. is described as first representative of Epallagidae from Baltic amber.

The authorship of Selys (1853) for the family-group name Euphaeidae is rejected, since the “légion Euphaea”…
