Orius?

Looks like Orius insidiosus (sp?). Anthocoridae family of true bugs. Probably either that or a similar species.

Orius insidiosus - insidious flower bug

I Googled images and feel that you've nailed it. The bug is sold commercially for use in thri*ps control. (Maybe that's what my photos show?)
http://www.extremelygreen.com/Product.cfm?Name=Thrips%20control%20(Orius%20insidiosus)

Another source mentions O. tristicolor is more common in the west, but I don't think that's what mine is. Any other opinions?

… Ron Hemberger, 10 January, 2007 - 6:10pm

different from the linked source

based on the picture.

… daike tian, 13 July, 2008 - 4:15pm

Agreed. See other comments, this date.

Arg, a pirate bug. And a sneaky one at that.

Neat! Thanks, Brad.

… Ron Hemberger, 9 January, 2007 - 9:35pm

should be more like Orius tristicolor

based on: http://www.nysaes.cornell.edu/ent/biocontrol/predators/orius.html

… daike tian, 13 July, 2008 - 4:13pm

Agreed.

Helpfully, both candidates are shown side-by-side in the link, and mine certainly does look more like O. tristicolor. Thanks, daike.

Orius insidiosus on my lotus flower

I found many these guys on my lotus flowers. Very tiny with L1.5-2W0.8mm. They are different from Orius tristicolor based on online sources more like insidiosus under checking by my portable microscope (very useful for me to identify insects and plants). I will take picture and post on it. Today I catched five and studied for one hr.

… daike tian, 13 July, 2008 - 5:12pm

I shot another a couple days ago and may post.

Same place and I think same thing. I have trouble seeing, let alone shooting these tiny guy. (Knee problems keep me from getting down low, and eyes are bad, too. Bummer!) Thanks for your help with this.

… Ron Hemberger, 13 July, 2008 - 8:22pm

look at mine

Hi, Ron, I just posted died pics, they are possibly Orius insidiosus.
On your picture three triangles connected but not on mine. I will shot alive ones someday... I can see them everyday, maybe found other sp.

thank for sharing IF.

Thank you for getting this moving again.

I certainly see a difference between your insects and mine. Thanks again, daike.

… Ron Hemberger, 14 July, 2008 - 5:32pm

post one again

it is alive on lotus flower petal should be better than died ones.
Really small, I have not found size larger than 2mm long
thanks for sharing inf,
