Pentas species

Pentas species;
Do Pentas bear male and female flowers ?: Do Pentas plants bear male and female flowers separately ?
Was looking through Pentas lanceolata posts.
Found that there shows two kinds of flowers; one with stamens, other with stigma.
Few posts listed:
showing both

with stamens

with stigma

Observed this red insect on the Pentas plant at my home. It was trying to hide under the leaves. Never seen this insect before.
This is a Sheild Bug [Pentatomid bug of Family Pentatomidae].
I think i saw these bugs a number of times but do not know the ID. Your post reminds me this bug once again and i tried to search the ID. How about the probability of the following ? -


Yes the bug in my post looks exactly the same as in the 1st link you have provided. I also gather from the links that it is a pest for some plants and useful to some other plants. From the 2nd link it is a Soyabean plant pest. Fortunately I have no Soyabean plants in my garden so need not worry :). Thanks again for the help. I have seen such green bugs in the past but never brown. The green bugs really stink.
