Trichocorixa reticulata
water boatman
Trichocorixa reticulata is a water boatman (family Corixidae) inhabiting saline and hypersaline aquatic environments. The species exhibits exceptional osmotic tolerance, surviving salinities from freshwater to full seawater (~3.5%). Populations show synchronized annual breeding cycles with peak reproduction in May-July. Females are larger than males, and eggs are deposited on solid substrates including algae and pool surfaces. Both adults and nymphs function as predators and scavengers.
