Cicadas |
| General recommendations. Cicadas are sizable, noisy insects with stout bodies, wide blunt heads, and large transparent wings. They emerge from the soil in mid to late summer, and spend much of their time thereafter in trees, where they molt and issue their sometimes startlingly loud mating calls. Some species' populations fluctuate cyclically. None cause serious damage to more mature trees in your yard and garden though small trees, especially young orchard trees, may suffer significant damage. |

Dog-day cicadas are hunted by female cicada killer wasps (Hymenoptera), which sting the cicada and lay an egg on it; when the the egg hatches, the larva feasts on the cicada
