Entomophagy among animals: The giant anteater is a mammal specialized in eating insects Entomophagy is widespread among many animals, including non-human primates . [ 3 ] Animals that feed primarily on insects are called insectivores .
As a feeding practice, hematophagy has evolved independently in a number of arthropod, annelid, nematode and mammalian taxa. For example, Diptera (insects with two wings, such as flies ) have eleven families with hematophagous habits (more than half of the 19 hematophagous arthropod taxa).

Even large mammals are recorded as eating insects; [5] the sloth bear is perhaps the largest insectivore. Insects also can be insectivores; examples are dragonflies, hornets, ladybugs, robber flies, and praying mantises. [8]: 31 Insectivory also features to various degrees amongst primates, such as marmosets, tamarins, tarsiers, galagos and aye ...
An Australian painted lady (Vanessa kershawi) feeding on nectar through its long proboscis. In zoology, a nectarivore is an animal which derives its energy and nutrient requirements from a diet consisting mainly or exclusively of the sugar-rich nectar produced by flowering plants.
Furthermore, mammals that weigh more than 18 ounces (510 g; 1.1 lb) usually cannot collect enough insects during their waking hours to sustain themselves. The only large insectivorous mammals are those that feed on huge colonies of insects (ants or termites). [196]
Before the era of widespread DNA sequencing, the grouping was used as a polyphyletic taxon for a variety of small to very small, relatively unspecialised mammals that feed upon insects. Since any primitive-looking fossil group of placental mammals was commonly assigned to this order for convenience, it was held to constitute the basal stock out ...
Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.
