• Eastern cicada-killers (Sphecius speciosus) are the large wasps which dig burrows each summer in well-drained lawns, playing fields, plant nurseries and sloping terrain with varying amounts of grass east of the Rocky Mountains in the US and south into Mexico, Guatemala and Honduras. ...
• The female cicada-killer on the right (click on the picture for an enlargement) is carrying a paralyzed annual cicada (Tibicen linnei) back to her burrow, where she will put it in a nest-cell, lay an egg on it and seal the cell. A grub will hatch from the egg in a few days, eat the cicada and overwinter underground in a hard cocoon which it weaves. ... The cicada-killer has adapted its life cycle to be in synchrony with that of its hosts: Like the several species of "annual" cicadas with which it feeds its young, a cicada-killer spends over 90% of its life underground as a larva. Like most hunting and parasitic wasps, the cicada-killer is a beneficial insect; it exerts a measure of biological control on cicadas, which damage shade trees by laying eggs under the soft bark of the new growth on the trees' terminal branches. Because they emerge each year in mid-July, cicada-killers are not signifficant predators of periodical (13- and 17-year) cicadas, which emerge in May and June and die off by mid-July. ...

• What is a periodical cicada?.
• All but a few cicada species have multiple-year life cycles, most commonly 2-8 years (de Boer and Duffels 1996). In most species, adults can be found every year because the population is not developmentally synchronized; these are often called "annual" cicada species. In contrast, the cicadas in a periodical cicada population are synchronized, so that almost all of them mature into adults in the same year. ...
• Some of the annual cicada species are sometimes mistaken for the periodical cicadas, especially those in the genera Diceroprocta and Okanagana; these other species emerge somewhat later in the year but may overlap with Magicicada. ... The best way to identify cicada species is by the sounds that they make, because cicada songs are nearly always species-specific. ... To learn about some of the common annual cicada species of eastern North America (including the genera Tibicen, Diceroprocta, and Okanagana), see our Michigan Cicadas Page.
• If a cicada lands on you it does so only because it finds you to be a convenient place to land -- unless you happen to be using a lawnmower or weed-whacker, in which case it might be attracted by the sound! Basically, periodical cicadas can hurt you only if they mistake you for a tree branch and try to feed, something that can happen only if you hold a cicada in your hand for a very long time (eventually this makes the cicada hot and thirsty). ...
• Cicada juveniles are called "nymphs" and live underground, sucking root fluids for food. ...
• Densities of tens to hundreds of thousands per acre are more common, but even this is far beyond the natural abundance of most other cicada species. ... Explaining the evolution of such an unusual life strategy is one of the most difficult problems for periodical cicada biologists. ...
• The table below is a guide to the approximate locations of periodical cicada broods. ...
• This year's population (17-year Brood X) is the largest of the 17-year broods, with cicada emergences expected in parts of fifteen states from New York to Georgia to Illinois. ... If you're interested in seeing a periodical cicada emergence, now is the time to act, because no cicadas are expected to emerge in 2005 or 2006.
