Gyretes

Gyretes er en slekt av biller i underordenen Adephaga, familien virvlere. De har todelte fasettøyne, den ene delen er tilpasset å se i vann, den andre til å se i luft. Når farer dukker opp kan de både dykke og gjøre hopp over vannoverflaten.


== Utseende ==
Middelsstore (ca. 6 millimeter), blanke, ofest mørkfargede virvlere. Kroppsformet er avlangt oval.


== Levevis ==
Virvlene er rovdyr og spiser insekter som faller ned på vannoverflaten. Disse billene opptrer gjerne i grupper som svømmer rundt på vannoverflaten, og kan minne om radiobiler i et tivoli. Dersom de blir truet dykker de og gjemmer seg nær bunnen. Om en virvler blir fanget, skiller den ut et illeluktende stoff. Dette gjør billen usmakelig for rovdyr og virker også som et alarmstoff overfor andre virvlere.


== Utbredelse ==
Slekten er utbredi i den neotropiske økosonen nordover til det sørlige USA.
