SAP BEETLE

Of those insects belonging to the family Nitidulidae (Coleoptera), only those living on flowers are regarded as pests. The great majority of species feed on pollen and sap. Coleoptera alive today have exactly the same characteristics as those that lived millions of years ago. This fact, confirmed by fossil discoveries, is an indication that the insects in question did not form in stages, in other words that they did not evolve.
