Hi Bugman,
I came upon several of these in my garden in South Surrey, BC, Canada in June, 2016. South Surrey is south of Vancouver, BC, near White Rock, just north of the USA border (WA State) — just in case your readers aren’t familiar with the local geography.
I had no idea what they are, but I think they look like your photo of a Sawfly larva. Are they harmful to plants or beneficial insects?
Thanks for your help.

Millipedes

Flatbacked Millipedes

Dear Jerry,
These are NOT Sawfly larvae.  They are Flatbacked Millipedes,
Harpaphe haydeniana, and according to BugGuide:  “This particular millipede secretes a dark fluid that has an odor similar to the almond extract used in cooking. Apparently this is a defensive manuveur. Millipedes also curl up in tight coils when threatened.  Caution: Many millipedes with bright color patterns secrete a compound containing cyanide. Wash your hands after handling them and do not allow children to pick them up.”  According to Island Nature:  “the millipede can perform its duty as a ‘macroshredder,’ breaking up plant material and initiating the process of nutrient recyclying [sic] in the soil ecosystem … . In fact, it plays such an important role in the process that it can be considered to be a “keystone” species.”

Thanks so much!
Keep up the GREAT work!
Jerry

I find so many of these around and in my house during the summer months. They’re maybe an inch and half long and dark brown with many legs. They have to antennae sticking out from the front (at least that’s what I think they are). I don’t know how they keep getting in or what I can do to keep them out.

Dear Sam,
Your image is not of the highest quality, but this appears to be a Greenhouse Millipede,
Oxidus gracilis, based on this BugGuide image.  According to BugGuide:  “Native to Asia, introduced to North America and found throughout the lower 48 states and southern Canada.”

Flatbacked Millipede

Flatbacked Millipede

Dear Fallistar,
We identified your colorful Flatbacked Millipede as
 Apheloria virginiensis corrugata on BugGuide where it states:  “Caution: Many millipedes with bright color patterns secrete a compound containing cyanide. Wash your hands after handling them and do not allow children to pick them up. ‘Millipedes are entirely non-toxic to humans and can be picked up by hand. Some secretions discolor the skin, but this wears away in a few days without lasting effect. Some large, cylindrical, tropical species squirt their defensive secretions up to a half meter (2-3 feet) and can blind chickens and dogs. Their fluids are painful if they get into the eyes, and persons working with tropical millipedes should be suitably cautious.’ ~Rowland Shelley”

Dear Barb,
There is a similar image on BugGuide, but we think yours has more attractive subjects.  We don’t know if this is a native Snail or an introduced species.

Image #1 was in the hallway at work, in my office in Santa Ana, CA on May 13, 2016 Baby Centipede? Image #2 (deceased) was taken as I entered my weekend retreat in Cherry Valley, CA. About a week earlier. I’m assuming is some type of centipede as well. Just wondering if either one is dangerous?

Multicolored Centipede

Multicolored Centipede

Dear Betsy,
The critter you found in your office is a Flat-Backed Millipede in the Order Polydesmida, which is pictured on BugGuide.  The other image from Cherry Valley is a Multicolored Centipede,
Scolopendra polymorpha.  According to Charles Hogue in Insects of the Los Angeles Basin:  “The bite of this species may be painful.  Although there are no data on the effects of its poison on humans, it is probably harmless.  Contrary to popular belief, the sharp claws on the legs are not poisonous, although the last pair of legs is capable of pinching.”  According to BugGuide, the common names are Tiger Centipede and Common Desert Centipede.

I would like your help on identifying three orange and black stripped bugs. I was in my yard searching for bugs, so I lifted up a rotting log and to my excitement I found three cool looking bugs all near each other! Pretty please with cherries on top help me identify them! :)
