Captured this under my stereo microscope. Much more beautiful than appearing on my camera sensor. Can someone help me identify it and explore more? Also is it having a compound eye ?

Location: New Delhi.

    $\begingroup$ I'm pretty sure it's a hemiptera, looks like a stink bug, though I don't recognize the color. And yeah, those are compound eyes. $\endgroup$

  • $\begingroup$ @DevashishDas New Delhi, I found it near my table lamp on first floor in evening, where I have kept some plants. Then I took a leafe, and gently placed it on it, and photographed under my microscope. I found that it became stable as soon as it came in contact with the leaf, otherwise it was moving here and there and jumping a lot. And thanks for the link. $\endgroup$

    $\begingroup$ @TheLastWord That's not the answer though, the question asks for species, and pentatomidae is the family name. $\endgroup$

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 "PK03") of the genus Eysarcoris

The Eysarcoris genus is present in India (e.g., see indiabiodiversity.org with example of "two-spotted sesame bug")

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.

It belongs to Pentatomidae family. More on the Wiki page

    $\begingroup$ That's correct, but pentatomidae is the family name, and the question asks for species. $\endgroup$

    $\begingroup$ The answer will be more useful for future reference if you add some rationale for your determination. $\endgroup$ Oct 15, 2014 at 21:28

To answer your other question about the eye:

Yes, shield bugs (Pentatomidae), like most insects, have compound eyes.

Also, the red dot medial and nearby the eye? That's an ocellus, a simple eye.
