Hi This is a small beetle (about 1/3 inch long). It is sitting on my house fence in Vancouver BC. I am curious to know what it is as I’ve not seen one before.

Dear Diane,
Based on this BugGuide image, this Stink Bug nymph is in the genus 
Chlorochroa.  According to BugGuide:  “19 spp. in 2 subgenera in our area [10 spp. reach Canada]” and “most species broadly oval, green to brownish or almost black, with pale whitish or yellow margin on pronotum and elytra; scutellum long & triangular, sometimes with 3 callosities (bumps) along base, and the tip usually pale or contrasting in color; membrane at apex of forewing often clear or translucent.”  We believe they may be Conchuela Bug nymphs, Chlorochroa ligata.
