Solenopsis invicta - the destroyer of picnics and bane of exposed limbs everywhere - is better known by its common name, the red fire ant. Aside from S. invicta's propensity to swarm and attack, it turns out this insect is also one of the more talented engineers in the animal kingdom.

A "meniscus"--the crescent-shaped and barely visible slope literally at water's edge--can mean life or death to an insect the size of a speck of dust. Water bugs that tiny must summon the energy to "surf" themselves up the problematic interface between liquid and solid in ponds and other wet places to escape predators or reproduce.
