1 Digitalis medicines control irregular heart rhythms (called arrhythmias) by slowing the signals that start in the sinoatrial (SA) node. 2  This, in turn, reduces the number of signals that travel through the atrioventricular (AV node). 3  Fewer signals mean fewer arrhythmias.
June beetle (genus Phyllophaga), also called May beetle or June bug, genus of nearly 300 species of beetles belonging to the widely distributed plant-eating subfamily Melolonthinae (family Scarabaeidae, order Coleoptera).
June bugs, also called May or June beetles, go through a life cycle that spans one to three years. Adult beetles emerge from the ground at the end of spring or start of summer. After feeding for several weeks, they lay their eggs in the ground. After two to three weeks, grubs hatch.
