I was wondering if you could help me with a discovery that I found in my pond. I was clearing out duck weed when I found what I can only describe as a stick insect running across the water. It is about 2cm long and it has 6 legs and 2 antennae on a long thin body.
I have searched lots and lots of websites but I still cannot find out what it is.

Water Scorpion

Water Strider or Water Scorpion???

Dear Katie,
This is a predatory, aquatic True Bug, and at first we thought it was in the family Nepidae whose members are commonly called Water Scorpions as they will deliver a painful, though not dangerous bite if they are carelessly handled.  When we reread your submission, we realized you stated it was  “running across the water.”  We apologize for the error, but since it was on top of the water, it is more likely a Water Strider in the family Gerridae.  We wish your images had greater detail.

Correction:  Water Measurer
Thanks to a comment we received, we now know that this is a Water Measurer in the family Hydrometridae and we learned on BugGuide that they are found “on emergent/floating vegetation along edges of ponds, marshes, and pools of slow-moving streams”
and that they feed upon “newly emerged, slow-moving, dying, or dead invertebrates (midges, mosquito larvae, bloodworms, ostracods, springtails, etc.)”  BioImages UK has some nice images.

I need help identifying this organism. This image is under 40x magnification under a microscope. It was pulled from a pond in East Central Texas, and appeared to be sucking water through its anus as a way over breathing in the water.

Hatchling Dragonfly Naiad

Hatchling Dragonfly Naiad

Dear Kendrick,
This appears to be a very young, perhaps recently hatched, Dragonfly Naiad.  There are many types of flying insects like Dragonflies, Damselflies, Stoneflies and Mayflies that have aquatic nymphs that are known as Naiads.  The water action that you observed is nicely explained by Charles Hogue in his excellent book Insects of the Los Angeles Basin:  “Human beings are latecomers in the use of jet propulsion.  by porcibly expelling water from its rectum, the dragonfly nymph can drive its body forward through the water at great speed.  This is an emergency method of locomotion that is employed principally to evade enemies.”

Dragonfly Naiad

This looks like the aquatic nymph of a Dragonfly, known as a Naiad.  Dragonfly Naiads are predatory, and we hope you are providing aquatic prey for it to eat.

Dragonfly Naiad

Dragonfly Naiad

Dear Destiny,
This is the aquatic nymph of a Dragonfly, commonly called a naiad.  It does not sting, however, it is a predator that feeds on aquatic insects and other small creatures, including small fish and tadpoles.

Found this crawling across a parking lot in Burns, OR. Looks almost cockroach-like, but doesn’t have antennae.

Toe-Biter

Dear Visiting in Burns,
This is a Giant Water Bug or Toe-Biter, an aquatic predator that can also fly from pond to pond in search of prey.
  The Giant Water Bug was our featured Bug of the Month in June 2008.

Water Strider

Water Strider

Dear John,
This is a Water Strider in the family Gerridae, a group of insects that are also known as “Pond Skaters, Jesus Bugs, Water Skippers” according to BugGuide, a North American insect website.  Water Striders skim across ponds and other bodies of water on long legs that distribute the insect’s weight so as not to break the tension of the surface of the water.
  Water Striders prey on insects that fall into the water.  Here is an image from the Insects of Thailand site.  We suspect your individual is immature as it does not have fully developed wings, but we cannot say for certain as we believe some species of Water Striders are wingless.
