Hydrovatus er en slekt av biller og tilhører familiegruppen vannkalver.

Utseende[rediger | rediger kilde]

Ganske små (1,8-4 millimeter), brede og høyt hvelvede, nærmest dråpeformede, halvmatte, gjerne rødbrunlige vannkalver.

Levevis[rediger | rediger kilde]

Artene lever langs bredden av vegetasjonsrike, mudrete dammer og innsjøer og holder seg på eller nær bunnen. De graver i bunnmudderet, og holder seg ofte på 1–2 meters dyp. De kommer sjelden opp for å puste og kan kanskje få tak i luft fra stenglene på vannplanter.

Utbredelse[rediger | rediger kilde]

Slekten forekommer i alle verdensdeler bortsett fra Antarktis.
