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 tenlined June beetle is widely found in sandy soils west of the Rocky Mountains. Larvae feed on plant roots and can weaken or kill the plant. Adults feed on foliage but do not cause economic damage to fruit trees. Infestations spread slowly because of a lack of movement by mated females and the long time span of each generation, which can be up to four years in the Northwest.
