Grasshopper love songs give insight into sensory tuning

.... They found that the OSEs of the receptors particularly matched characteristic features of species-specific acoustic communication signals used by grasshoppers to attract mating partners.

Locusts' built-in 'surface analysis' ability directs them to fly overland

... swarms were predominantly directed by prevailing winds. Now, Hebrew University of Jerusalem scientists have shown that a physiological trait of these grasshoppers ?namely their polarization vision -- provides them with a built-in source of "surface analysis" ?a discovery that could pave the way for efforts to ef...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...nal oxygen that can cause oxidative damage -- the destruction of biomaterial due to excess oxygen -- to tissues. To protect their bodies, insects like grasshoppers discontinue breathing. "We propose that most insects stop breathing in order to lower their internal oxygen concentration to physiologically safe l...
