A Praying Mantis hunting around a barn in Fieldbrook, California. READ MORE- The Praying Mantis is quite an unusual creature. They are very well designed for their ambush hunting style, with keen eyes and grasping arms, they can grab any eat everything from tiny insects to small birds.
Their compound eyes contain up to 10,000 ommatidia, which contain clusters of photo-receptor cells. These cells provide the Mantid with amazing movement capture. A small area in the front of the eyes called the fovea has the greatest visual acuity, and provides the best method to lock onto prey. The mantis can move it's head to keep the target in the center of this focus area. Their eyes are situated so they have a very large field of view. They can turn their heads 180 degrees, so it's hard to sneak up on them.
One interesting note is that there are usually small dark spots that we see in each eye, which are called "pseudopupil" which are actually the Ommatidia that we are seeing straight on. These are not actual pupils, but absorbed light creates a crazy effect.
They most often hunt during the day, but can be seen flying in the evening and nighttime, often heading towards lights on houses. When flying at night, many mantids can sense the echolocation of bats and change their flight paths to avoid being eaten..
Most mantids live less than 6 months after they hatch from very interesting egg cases that are often found on the sides of houses, wooden fences, grasses and trees. The egg cases appear as a hardened foam like material called an Ootheca. The egg case usually contain between 20 and 200 eggs. The young Mantids hatch from these egg cases and immediately begin stalking prey. They appear like mini versions of adults, but will grow and molt many times before becoming adults. They will emerge with wings for flight during the final molt.
They are famously known for the females eating the males after mating, which happens, but not as often as once believed. Killing the male is not necessary for mating, it usually just depends on how hungry the female is at the time! Mantids are almost always capable of eating other mantids through their entire lifespan, including members of their own species. This is due in part, from their voracious appetites, and stalking anything that moves.
There are many different species of mantids, and many are specialized to look like flowers or sticks or leaves in order to increase their hunting success. There are around 1500 known mantid species in the world, with around 20 species living in the US. Some are native, and some introduced.
These are amazing insects to watch during the late summer and fall. They are relatively large insects at 2-5 inches long, and have interesting motions as they hunt. They can be handled, but it is best to leave them alone, as they are capable of biting, but it is very unlikely.
Look for them and admire them as a wonder of the insect world!
