Huh, I always thought they lived off the stored reserves when they came above ground until running out. This was reinforced by finding dead cicadas with hollow abdomens -- turns out male cicadas have a mostly empty abdomen that is used to amplify their mating calls!This says:
They drink sap from tree roots and branches as the adults we see, as nymphs they start out the size of a grain of rice and go after grasses and smaller plants. Pretty cool.
Soon, Steve. Ours have been coming out for a week, despite all the rain. As of yesterday, the sound has started, but it's not very intense yet. My Blacksburg friends haven't seen any yet, but this morning, for the first time, they started to hear them.I haven’t I seen them yet, but we have had a lot of rain.
Talked to the folks last night -- they're out in force in both Ironto and Roanoke.Re feeding: they are bad news for orchards and young trees. In fact, they recommend not planting young trees in the year preceding the influx. They also feed on large trees (sap, as mfturner said), but to lesser impact. What I've noticed in previous invasions is that there will be brown areas on mature trees. The whole tree will be green, except for the leaves at the ends of some of the branches, which gives the trees a spotted look. When we get to that stage, I'll post pictures.
