Just googled tarnished plant bug and sincerely wished those bugs are not it. I know very little about bugs. I just hope it's not something nasty for plants, as I have all my succulents outside on the balcony.

I only read 'bits & pieces' about bugs, but many are more plant specific-perhaps not only one, but probably related plants. Hopefully this is the case & they won't feed on your succulents. In colder regions like where I live, bugs may be seeking hiding places to overwinter. Maybe it is different in warm climates where you are. I am just speculating here! If I was concerned, I would watch for any eggs.

If you find out what it is, pls. post.

(Found Dysdercus sp. - Cotton strainers - that looks a lot like your bug, but have different color striped belly...now it is bugging me! :)

Rina, you nailed the genus, I believe. Further googling showed similarly colored bug called Dysdercus chaquensis. I really do hope they don't like succulents.. ;p

Most true bugs feed on flower nectar and fruits of plants, which is not of much concern for succulents. I believe they sometimes eat decaying matter as well.

Pheww.. that's good to hear. :D

Actually most true bugs feed on sap they suck from plants, aphids being a well-known example. I wouldn't be worried about these bugs on your plants, since 1) most true bugs have specific host species or genera, as Rina indicated ; 2) they are big and obvious! and 3) there's only two of them (I hope!)

breton2, regarding #3, actually there are MANY of them, those 2 just happened to be in my line of sight when inspecting my plants.. >_< It's inevitable really, because of the many trees in the surrounding area. I'll keep both eyes on them! ;P

Ha, well at least they big and easy to spot!

Going forward, watch out for eggs. They're probably going to be orange clumps and look like tobiko...er...roe? Fish eggs. Those little buggers will not discriminate. But soap water alone will kill them.

Oooh, I like tobiko.. (wrong focus, hehee)..

New trend - instead of 'flying fish eggs' one can get 'flying bugs eggs', haha...

I think the former is MUCH more appetizing for some reason.

Hmm, after insect flour, the eggs maybe the next superfood... (°_°)
