picture and names of bugs can be found in THIS thread.

And in the Plant Tycoon Guides.

I just got the shiny flower beetle and here is a partial list of the flowers in my greenhouse:
jalapa lemonbush
nox orchid
rosaceae orchid
mystic orchid
viola orchid
nox astera

There was at least one other plant in my greenhouse that hadn't produced buds/flowers so I am not sure if it is the "special plant" or not

okay I just went back and read the other posts and pp miniflowers had suggested looking at the foliage in the jar with the bugs. The shiny beetle in in a jar with gladiatus foliage (I think) of course I didn't have any of those in my greenhouse, but some of the flowers I did have were crosses bred from a gladiatus. Hmmmm interesting

As I'm still missing 4 bugs, I got the Rare Golden Spider. It was placidly walking between 2 pots of Mela Rare Oak! But I don't know if it's the plant it prefers or if it's random!

RARE shiny flower beetle = Tier 3 Flowers on Orchids.

It worked for me! ^_^

I found that one by luck. it says uncommon but it was harder to find than some of the rare ones.

i'm trying to breed all the different orchids and i had different ones with tier 1, 2, and 3 flowers. i went to the nursery to do some selling, and when i came back, the shiny flower beetle came creeping out from behind one of my orchids.

two more bugs to go!

Well done sunflower. maybe the orchids bring it out. I'm missing 4, but i know two will be out with my tier 4 plants.

One of my friends who is playing at my house, came, twice and has opened the game TWICE and has already found 24 bugs, she just got lucky
