  Description

  
  

  Wing length: 6mm. The fulvous and white patterning is typical of Eristena but rather more pale areas than most spp. Sexually dimorphic. Murphy (1989 figs. 1-5) gives descriptions of three Singapore Eristena spp.

  Singapore, Brunei, China. Mangrove forests.

  Life History & Pest Status

  
  

  The adults are gregarious, clustering under mangrove foliage, and will swarm and regroup when disturbed.
  
  The aquatic larvae bear breathing filaments all over the body, and build tubes in drainage channels under rotting leaves in mangrove swamps and feed on Dictyota spp. (filamentous brown algae) (Dictyotaceae), which they partially use for the tube. See RTS 1994.
