what is meant by the 'second' mentioned mimicry?
It is anatural phenomenon in which two or more well-defended species, often foul-tasting and that share common predators, have come to mimic each other's honest warning signals, to their mutual benefit.

where do wasps fit in the food chain UNANSWERABLE how are these creatures classified as per the scientific classification in the animal kingdom? It is an insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; have there been any petrified remains of this creature recovered, which proves its existence millions of years ago? Hymenoptera in the form of Symphyta (Xyelidae) first appeared in the fossil record in the Lower Triassic. Apocrita, wasps in the broad sense, appeared in the Jurassic, and had diversified into many of the extant superfamilies by the Cretaceous; they appear to have evolved from the Symphyta. Fig wasps with modern anatomical features first appeared in the Lower Cretaceous of the Crato Formation in Brazil, some 65 million years before the first fig trees. are these creatures further grouped depending on their social characteristics? Yes into social and solitary wasps ? what are the social characteristics of the first group mentioned above? Of the dozens of extant wasp families, only the family Vespidae contains social species, primarily in the subfamilies Vespinae and Polistinae. With their powerful stings and conspicuous warning coloration, often in black and yellow, social wasps are frequent models for Batesian mimicry by non-stinging insects, and are themselves involved in mutually beneficial Mülleri mimicry what is meant by the 'first' mentioned mimicry? It is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both what is an example of it which portrays this mimicry? An example of this is the fly "Spilomyia longicornis", which mimics vespid wasps

Müllerian mimicry [SEP] Introduction
Müllerian mimicry is a natural phenomenon in which two or more well-defended species, often foul-tasting and that share common predators, have come to mimic each other's honest warning signals, to their mutual benefit. This works because predators can learn to avoid all of them with fewer experiences with members of any one of the relevant species. It is named after the German naturalist Fritz Müller, who first proposed the concept in 1878, supporting his theory with the first mathematical model of frequency-dependent selection, one of the first such models anywhere in biology. Müllerian mimicry was first identified in tropical butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals including poison frogs and coral snakes.
