Ischnura senegalensis

IUCN lists Ischnura senegalensis as extremely widespread and with high tolerance for disturbance and pollution. It occurs from South-Africa to Japan. Vietnam is no exception. This is a common species, nowhere really abundant, but always present, in rice fields, ditches, verges of ponds, wet grassland and so on. It is rather similar to various other Ischnura species, but in Vietnam it is easily set aside from the orange species. The female is also readily recognizable, with the dark dorsum of the synthorax, a pattern also found in the much smaller Agriocnemis species like A. femina, but size readily sets them apart.
