===Migration===
{{Main|Insect migration}}

Many beetle species undertake annual mass movements which are termed as migrations. These include the pollen beetle ''[[Meligethes aeneus]]''<ref>{{cite web |url=http://www.fwi.co.uk/arable/half-of-the-uk-sees-start-of-pollen-beetle-migration.htm |title=Half of the UK sees start of pollen beetle migration |author1=Allison, R. |date=2015-03-17 |access-date=2017-03-16}}</ref> and many species of [[Coccinellidae|coccinellids]].<ref>{{cite journal |doi=10.1111/j.1469-185X.1962.tb01609.x |title=Migration of Terrestrial Arthropods in Relation to Habitat |journal=Biological Reviews |volume=37 |issue=2 |pages=171–211 |year=1962 |last1=Southwood |first1=T.

A 2008 study of an unusually large outbreak of Mountain Pine Beetle (''[[Dendroctonus ponderosae]]'') in [[British Columbia]] found that beetles were capable of flying 30–110&nbsp;km per day in densities of up to 18,600 beetles per hectare.<ref>{{cite book |title=Migration: The Biology of Life on the Move |author1=Dingle, H. |date=2014 |publisher=Oxford University Press}}</ref>
