An insectivore is a carnivorous animal or plant that eats insects. [1] An alternative term is entomophage , [ 2 ] which can also refer to the human practice of eating insects . The first vertebrate insectivores were amphibians .
For some time it was held that the remaining insectivoran families constituted a monophyletic grouping, or clade, to which the name Lipotyphla had long been applied. However, molecular evidence indicated that Chrysochloridae ( golden moles ), Tenrecidae ( tenrecs ), and Potamogalidae ( otter shrews ) should also be separated as a new order ...

Entomophagy is widespread among many animals, including non-human primates. [3] Animals that feed primarily on insects are called insectivores . Insects, [ 4 ] nematodes [ 5 ] and fungi [ 6 ] that obtain their nutrition from insects are sometimes termed entomophagous , especially in the context of biological control applications.
Historically, these animals were grouped with others such as treeshrews, elephant shrews, and colugos, under the broader category Insectivora, comprising all small insect-eating placental mammals. Wilhelm Peters identified two sub-groups of Insectivora, distinguished by the presence or absence of a cecum in the large intestine. [ 3 ]

Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
As its name suggests, the bat species' nose is long with a leaf-like projection. The long-nosed bat lives on nectar and pollen. Similar to a hummingbird, the long-nosed bat can hover while it ...
