The Perfect Predator

One very warm day this summer I was lucky enough to observe a praying mantis (Mantis religiosa) in my back butterfly garden. I watched  attentively for some time as  the insect made himself at home within the stems of the tall perennials. This one was relatively small as a mantid goes, measuring only a few inches at most.  I remember seeing some as a kid that were much, much larger, but I suppose it could just have easily been that I was much smaller. However, I do still remember my amazement when, as a kid, I first observed one turn its head and look back directly over its shoulder at me. Good thing I was not easily spooked. But enough of my detour into childhood memories.

This day, after posing for some pictures on this flowery brightly colored background, this mantis climbed down within the brown speckled stems of my Echinacea and Eupatorium and “became one” with its surroundings. The shape of the insect’s body and its coloration provided the perfect camouflage.

It then proceeded to perch in that position with little movement for quite some time lying in wait for some unsuspecting victim to wander into its attack zone. After about 2 hours (no, I did not sit there watching it for the entire time as there is way too much work to be done in my garden) I was rewarded with the opportunity to watch as a red milkweed beetle rambled just a little too close. In a lightning fast movement the mantis snatched the beetle, grasping it with its spiked forelegs.

Since the praying mantis is an insect that feeds on living food it held the struggling beetle securely in its legs and wasted no time in taking its first bite. It brought back memories of those bad horror movies on Hallowe’en eve (you know, the ones that used to air annual on WLVI Ch. 56?). Watching the display it was quite clear that the mantis is quite the fearsome hunter and could be, possibly, the perfect predator.

Some interesting facts about the praying mantis:

  • It is named for the prayer-like position in which it holds its front legs
  • It can turn their triangular heads up to 180 degrees
  • While they are mating, the female praying mantis may eat the head of its mate – not the type for a long-term relationship I think…
  • The praying mantis has excellent eyesight and can see up to about 50 feet away
  • The praying mantis found commonly in New England is not native to this country – it is from Southern Europe. It will grow to a length of 3 inches
  • The European Mantis (mantis religiosa) although not native to this country became the official State Insect of Connecticut on October 1st, 1977
  • The other mantis found in Massachusetts is the Chinese mantis (Tenodera aridifolia) introduced into the Northeast in the 1890s to help control insect pests – it will grow up to 5 inches in length and has been known to prey upon small mammals and birds

White-tailed Deer

White tailed deer  (Odocoileus virginianus)

This is one of the white-tailed deer from the herd that routinely spends time foraging in our yard. They love the edge of the pond as it has plentiful grasses and one of their favorite treats – yellow nut-sedge. This year the herd totaled four; two older does, a yearling, and one fawn. The herd is most frequently seen at dawn and dusk but can be present  any time of day.  This summer they usually could be seen at mid-day during the hottest days of July and August. The abundant shade and food makes our back yard a preferable place to nap and eat (especially when the apple tree is loaded with fruit).

Some interesting facts about the deer:

  • They have hollow strands of hair that help them remain insulated from extremes of temperature and also prevent them from drowning
  • Since fawns do not have a scent, they remain undetected by the enemies – this is often why a doe will leave a fawn unattended in a shady/wooded place (or even in your back yard)
  •  There is only species of deer in which the female also has antlers, the Reindeer (Caribou). The male deer or “stag” sheds their antlers every year
  • Deer can be found on all continents, except Antarctica and Australia
  • The origins of the name come from the Middle English word ‘der’ meaning beast and  from the Old English word ‘dor’
  • They have a four chambered stomach that allows them to digest tough plant foods.  Deer will eat quickly without much chewing and will later, as they rest, cough it up (regurgitate) and chew it
  • Exceptional jumpers, they can clear an 8-foot hurdle from a standing position
  • They are excellent swimmers and have been clocked at speeds up to 13 miles per hour
  • White-tailed deer are known to eat over 600 species of plants in North America
  •  Their long noses possess an intricate system of nasal passages with millions of  receptors (up to 297 million). By comparison, dogs have 220 million and humans just 5)
  • They lick their nose to keep it moist. This allows odor particles to stick to it which improves their sense of smell
