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 June bugs feed on the leaves of trees and shrubs, making them a pest for gardeners. June bugs can cause patchy, tattered foliage that weakens or occasionally kills the plants they have fed upon. June bug grubs do not eat foliage, but they do eat roots and organic matter from the soil. The grubs can occasionally damage lawns and harm crops such as corn, potatoes or strawberries. June bugs and Japanese beetles share a similar appearance and life cycle, but they are separate species.
