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).
The June beetles tend to mature in June, and they are complete adults at that time. So it takes a complete year for them to emerge by spring time. The June bugs are nocturnal because they get attracted to the light, and their lifecycle lasts about three years. The first year of their life is spent underground.
