The Art of Grabbing Mates

Fifth place in the 2016 Nikon Small World Photomicrography contest goes to Igor Siwanowicz for this stunning image of the suckers on the tarsi of a male diving beetle (Dytiscidae). Male diving beetles are known to latch onto female beetles as a form of mate guarding. The males also eat some of the food captured by the female beetles. This aspect of the relationship is parasitic and females can benefit by dislodging the male. The cuticle of female beetles has adaptations to resist adhesion by males. This has led males to add multiple means of attachment to females. This is evident from the stunning diversity of the suckers.
