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).
What Do June Beetles Eat ? June bugs are widely prevalent in North America. June bugs exist in the form of grubs when they are in the stage of larvae. The larvae come out with short hair and this aids in their movement. The eggs from which the grubs emerge are laid during winter, and thereafter the grubs make their way to the surface during spring, when they start feeding actively.
