What is the scientific and common name of this bug?
Definitely appears to be Pentatomidae (as others have pointed out) due to shield-like, broad bodies. With over 4500 species and larval stages demonstrating significant variability even within species, ID can be difficult without knowing specific fauna, size, habitat, etc.
The OP doesn't list a size, but because OP is viewing under a scope, I assumed this is a fairly tiny species.
I came across this similar-looking unknown species (simply labeled &quot;PK03&quot;) of the genus Eysarcoris

The Eysarcoris genus is present in India (e.g., see indiabiodiversity.org with example of &quot;two-spotted sesame bug&quot;)
A similar species well known throughout Europe is Stagonomus venustissimus (previously classified as Eysarcoris):

I cannot say if either of these species is correct (doubtful), but I think they are closer than the other provided answer.
I'll update if I find anything specific.
