Coleopterans are normally called beetles. They are insects with thick front pair of wing covering the rear wings. Brown and black are the common colors of beetles, but some have very bright colors too. Encyclopedia says it comprise 40% of all the insects and that means at least 360,000 species are all beetles. Oh My God, i hope that 360,000 will not be roaming here at the same time, that is really more than scary!
Look at that thick hard-shelled body and appendages, scary isn't it.
And look at that fierce face, it really is more than scary! The mandibles also look ready to tear every part it alights on. I am glad this night visitor is just greater than one inch long, or else i would have screamed!
