Editing Diapause (section)

===Termination===
In insects that undergo obligate diapause, termination may occur spontaneously, without any external stimuli.<ref name="Kostal" /> In facultative diapausers, token [[stimulus (physiology)|stimuli]] must occur to terminate diapause. These [[stimulus (physiology)|stimuli]] may include chilling, freezing, or contact with [[water]], depending on the environmental conditions being avoided. These stimuli are important in preventing the insect from terminating diapause too soon, for instance in response to warm weather in late fall. In the [[Edith's checkerspot]] butterfly, individuals must receive enough sunlight in order to terminate the diapause stage and become a fully grown butterfly.<ref name="ten">{{cite journal |last1=Weiss |first1=Stuart B. |last2=White |first2=Raymond R. |last3=Murphy |first3=Dennis D. |last4=Ehrlich |first4=Paul R. |title=Growth and Dispersal of Larvae of Checkerspot Butterfly Euphydryas editha |journal=Oikos |date=October 1987 |volume=50 |issue=2 |pages=161–166 |doi=10.2307/3565996 |jstor=3565996|bibcode=1987Oikos..50..161W }}</ref> Termination may occur at the height of unfavourable conditions, such as in the middle of winter. Over time, depth of diapause slowly decreases until direct development can resume, if conditions are favourable. Termination can also occur in specific time frames linked to reproductive periods, such as in the beetle ''[[Colaphellus bowringi]]:'' diapause ends for spring-reproducing beetles between late February and early April and for autumn-reproducing beetles between mid August and early October''.''<ref>{{Cite journal |last1=Xue |first1=Fang-Sen |last2=Li |first2=Ai-Qing |last3=Zhu |first3=Xing-Fen |last4=Gui |first4=Ai-Li |last5=Jiang |first5=Pei-Lan |last6=Liu |first6=Xiao-Fen |date=August 20, 2002 |title=Diversity in life history of the leaf beetle, Colaphellus bowringi Baly |url=https://www.sciengine.com/AESK/doi/10.16380/j.kcxb.2002.45.4.494498;JSESSIONID=737db758-13f2-4432-a9aa-1297abd9b7ed |journal=Acta Entomologica Sinica |volume=45 |issue=4 |pages=494–498|doi=10.16380/j.kcxb.2002.45.4.494498 |doi-broken-date=1 November 2024 }}</ref>
