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).
Adult beetles are Â¾ to 1 inch long. The adultâs upper body is velvety green to dull brown with lengthwise stripes of green with yellow-orange margins on the hardened front wing. The underside of the body is shiny metallic green or gold. Adults also have a distinct, small, flat horn on the head (Fig. 2). Green June beetle grubs are 3/8 (first instar) to 1Â½ inches long with a white stubby body and short legs.
