The Praying Mantis: Predator of the Garden (2024)

The praying mantisisaninsect that has fascinated humans for centuries. A master predator in the garden, mantidshave an abundance of lore surrounding them—including whether they eat hummingbirds. Here aresome of our favorite facts and folklore about prayingmantis.

Mantis orMantid?

We’ve often been asked about the difference between “mantis” or “mantid”? “Mantis” refers only to members of the genus Mantis, like the European mantis, Mantis religiosa. “Mantid” refers to all and any species. In common usage, the terms are essentially used interchangeably and we say, call it what you wish.

What Do Praying MantidsEat?

• Often considered a beneficial insect, praying mantidsare actually “generalists” (i.e., willing to eat a variety of things)that preyon both bothersome insects and beneficialones.
• A carnivore, mantids dine primarily on insects like flies, crickets, moths, grasshoppers, and mosquitoes. They can even feast on prey over three times their size, including small animals such as frogs, lizards, and—yes—evenhummingbirds.
• Because of their voracious appetite for insects, praying mantids are sometimesconsidered a friend to farmers and gardeners, since they work wellas a natural form of pest control. However, keep in mind that they will eat the good bugs,too!
• These insects will even eat each other! In fact, praying mantids are famous for being cannibalistic: afemale will sometimes eata male just after—or evenduring—mating.
• Although they may eat other beneficial insects (and, occasionally, each other), their preference is for theinsects that coincidentally do the greatest damage to crops, such as grasshoppers, beetles, and other smallinsects.

Non-Native Mantids andHummingbirds

Recently, mantids have gained some notoriety for preying on larger animals such as lizards or small birds. Generally, the species of mantids native to North America—including the Carolina mantid (Stagmomantis carolina)—are not large enough to take on prey as big as hummingbirds.

However, there are several non-native species—introduced in the 1800s to help control insect pests—that have become naturalized in North America. The Chinese mantis is one of the most widespread and the largest, growing up to 4 inches in length. This species in particular, perhaps in part because of itssize, has been known on occasion to catch a hummingbird at a feeder, especially if it is very hungry or if it mistakesthe bird for a bee or other insect that seeks the sugarwater.

To avoid this unfortunate occurrence, move any hummingbird feeders away from surrounding bushes and branches, so that the mantidsare easier for the birds to see. It also can help to add a broad cover over the top of the feeder, to discourage mantids that cannot fly. If you do see a mantidon the feeder, coax it onto a stick and move it gentlyaway.

The other prominentnon-native mantid in North America is the European mantis, Mantis religiosa. This mantidissmaller than the Chinese mantid and is generally not a threat tohummingbirds.
