Green Stink Bug

Posted on by

“Stinkbug” is the common name for a family of insects. There are thousands of species, found in most parts of the world. Stinkbugs are so named because they secrete a foul-smelling liquid that is repulsive to most predators. Most stinkbugs are dull in color, usually gray or brown, but some are such colors as brilliant green – like this one I saw today.

These insects are also sometimes known as “Shield Bugs,” because of their shape. Adult stink bugs hibernate in order to survive the winter. In the fall I often see Brown Stinkbugs sunning themselves on my house and shed, catching the last warm rays of sun for the year.

Like a skunk, a stinkbug will only give off a very bad smell if it is bothered. To most predators, a stinkbug tastes as bad as it smells.

Water Strider

Posted on by

Spring is just around the corner. It was 70 degrees and pleasant today. Many people were walking around, enjoying the weather. I decided to check out a vernal pool where frogs and salamanders will soon be migrating to. Since it is fishless, it’s a good place for the amphibians to lay their eggs. Although I didn’t see any frogs or salamanders, an insect skimming across the water caught my eye.

Water Striders are able to skate on top of water due to a combination of several factors. They use the high surface tension of water and their long legs (which give them an even distribution of weight) to help them stay above water. New research reveals the Water Strider’s legs are covered with microscopic hairs that trap tiny air bubbles, allowing the insect to simply float.

These insects live on the surface of ponds, slow streams, marshes, and other quiet waters. They have very good vision and move quickly on the water. The short front legs of a Water Strider are for grabbing prey (often mosquitoes, their larva and other small insects).

Water Striders can live for many months and adults can overwinter. They crawl inside plant stems and seek other forms of shelter when it gets cold. Other common names for Water Striders are: water bugs, magic bugs, pond skaters, skaters, skimmers, water scooters, water skaters, water skeeters, water skimmers, water skippers, water spiders and Jesus bugs.

Eastern Toebiter

Posted on by

Perhaps the most fearsome freshwater invertebrate in North America is the Toebiter. It has paddle shaped hind legs for swimming and raptorial front legs for catching prey. It is classified as a “true bug.” One of the criteria for true bug designation is the presence of a piercing, sucking mouthpart.  Toebiters cannot chew.  Instead, they pierce their food with their beak-like mouth, pump saliva into the food source to partly digest it, and then suck it out, as if using a straw.

Unlike many insects, whose eggs are abandoned by the adults, toebiter eggs are glued to the surface of the male’s outer wings and cared for and protected by the male until they hatch.

Toebiters occur in ponds and lakes, where they rest below the water’s surface. There are two tail-like breathing tubes at the rear end of the toe-biter that help it to breath while underwater. When it needs air, it extends the breathing tubes.

During mating season they fly from pond to pond. It is during these flights that these insects fly to lights, earning their other common name, “Electric Light Bugs.” Still another common name is the “Giant Water Bug.” The Eastern Toebiter is one of the largest insects in the U.S. and Canada. Below is an example of one that flew into our campsite when we were staying at Myrtle Beach in the early 1990s. It was photographed next to a cigarette pack for a size reference.

Toebiters are capable of inflicting a painful bite with their strong beak. They prey on aquatic insects, small fish, frogs, tadpoles and other organisms. They often play dead when threatened.

They are a fun and easy-to-keep insect pet. The type in the above photos have only eaten fish for me, but there’s a smaller type of toebiter in the Northeastern states that eats crickets, snails and mealworms readily. Here’s one that I kept for about a year, eating a cricket.

I keep mine in a large glass jar with a stick that they enjoy resting on, as well as some aquatic plants. They spend most of their time poised in a praying mantis-like way, waiting for food to swim by. They can live in groups if they’re about the same size – I have two toebiters. 

Don’t fret if you live in the western United States, because toebiters live there too. Here’s one that I found in a creek in Gilroy, California in 2007.
