In a bush filled with recently emerged Hexegenia, I came across this guy that I’m having difficulty identifying.
Location: eastern Manitoba, Canada (Lac Du Bonnet area).

Dear Darrell,
This looks like a member of the order Diptera, and we wrote to Eric Eaton for assistance, but in the meantime, we continued to research and we found this Green Midge from Canada pictured on BugGuide.  We believe this is a Midge.  Here is another BugGuide image but this individual is from California.

Robber Fly with Prey

Dear Christie,
This is a predatory Robber Fly, probably a member of the genus Promachus, a group whose members are called Giant Robber Flies or Bee Killers according to BugGuide.  It might be
Promachus bastardii based on BugGuide images.

Possibly Elm Seed Bug Infestation

Dear Always Curious,
These are definitely True Bugs and they appear to be immature nymphs, which sometimes makes exact identification difficult.  If you are able to send an image of a winged adult, that might help.  Our first impression is that this might be an infestation of Elm Seed Bugs, an invasive, introduced species that has spread in Washington, Idaho and Utah as well as Oregon according to BugGuideHermiston Herald does include an image of a nymph that looks very similar to what you have submitted.  We would not rule out that it might be an infestation of another invasive species, the Mediterranean Seed Bug.

Possibly Elm Seed Bug Infestation.

Oh m’gosh Thanks so much for the reply! I bet they are elm seed bugs as there are many elms around and many are diseased.
My gratitude!

We have 1000s of these in and out of our home. Do you know what it is? They are very small, less than 1/2″.

Elm Seed Bug

Dear JRW,
This is an Elm Seed Bug,
Arocatus melanocephalus, which we identified on BugGuide.  According to BugGuide:  “Native to, and widespread in S. & C. Europe, established and spreading in w. US (first detected in Idaho 2012)” and “Invades homes during summer, may stay through the winter.”  Based on BugGuide data, Utah is a state that has experienced infestations.  According to Utah State University Extension:  “There’s a new bug in town. Since July 2014, Utah State University Extension’s Utah Plant Pest Diagnostic Lab has received numerous calls about a small, brown and black insect gathering in and on homes. The elm seed bug, a native of Europe, was first identified in the United States in Idaho in 2012 and in Oregon in 2013. While the first samples from Utah came from Salt Lake County, the insect is likely well established along the Wasatch Front and Cache County.  Elm seed bugs feed mostly on elm seeds, but can be found on other trees, such as the linden. Luckily, the bugs are not a concern for the health of elm trees, but they have become a nuisance pest, similar to boxelder bugs, by entering homes and buildings in the spring, late summer and fall. However, unlike boxelder bugs, these bugs can emit a pungent smell, similar to bitter almonds, from their scent glands.”  Introduced species without natural predators pose a significant threat to native ecosystems.

Hi guys,
This beetle was on the front walk this evening. I think it is a Triceratops Beetle, but I am not sure.
What do you think?

Hermit Beetle

Dear John,
This is not a Triceratops Beetle.  It is a Hermit Beetle,
Osmoderma eremicola, based on images posted to BugGuide.  Did you detect the smell of leather when observing it.  According to BugGuide, it is also called Odor of Leather Beetle:  “for strong odor of ‘Russian Leather'”.

Hermit Beetle

Hi Daniel,
Thanks for the identification.  I did not detect a leather odor, but that may be because there was a lingering skunk odor from the previous night.

This bug was caught chasing my husband as we swam in a lake. It has what looks like feathers along it’s back side and pinchers.

Mayfly Nymph

This is the aquatic nymph or naiad of a Mayfly in the order Ephemeroptera.  Anglers often devote major portions of websites to insects used as bait, so we found nice images that match yours posted to Fly Fishing God and Trout Nut as well as on BugGuide.  According to BugGuide:  “most nymphs develop in streams and rivers that are well-oxygenated and relatively free of pollution; some species develop in lakes or ponds, usually in shallow water where the oxygen content is highest.”
