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 sow bug (also known as the woodlouse, roly-poly, or pillbug), though often lumped in with centipedes and millipedes, is not a Myriapod but is actually a type of land-dwelling crustacean, related to lobsters, crayfish and crabs. The sow bug is brownish-gray in color and usually reaches no more than 3/4 of an inch. It has an oval-shaped body with a series of overlapping plates on its back, resembling a small armadillo or turtle. A sow bug typically has fourteen legs. Like centipedes and millipedes, sow bugs prefer a moist environment.
