In the past, the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British English insectology implies the study of the ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.

Not all species of insects have frontal sutures, but in those that do, the sutures split open during ecdysis, which provides an opening for the new instar to emerge from the integument. The frons is that part of the head capsule that lies ventrad or anteriad of the vertex. The frons varies in size relative to the insect, and in many species ...
Myrmecology (/ m ɜːr m ɪ ˈ k ɒ l ə dʒ i /; from Greek: μύρμηξ, myrmex, "ant" and λόγος, logos, "study") is a branch of entomology focusing on the study of ants. Ants continue to be a model of choice for the study of questions on the evolution of social systems because of their complex and varied forms of social organization.
The largest study of insect declines to date gives us the best indication of how species all over the world are faring. Insects: worldwide study reveals widespread decline since 1925 Skip to main ...
This concept is essential to the study of insect ecology. Coevolution is particularly important in how it can lead to both micro- and macro-evolutionary changes. Micro-evolutionary changes include shifts in genome and alleles while macro-evolution is the emergence of a new species, also called speciation . [ 51 ]
Lepidopterology (from Ancient Greek λεπίδος (lepídos) 'scale' πτερόν (pterón) 'wing' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies. Someone who studies in this field is a lepidopterist or, archaically, an aurelian.
