Editing Tettigoniidae (section)

===Stress response===
In species which produce larger food gifts, the female often seeks out the males to copulate. This, however, is a cost to females as they risk predation while searching for males. Also, a cost-benefit tradeoff exists in the size of the spermatophore which the male tettigoniids produce. When males possess a large spermatophore, they benefit by being more highly selected for by females, but they are only able to mate one to two times during their lifetimes. Inversely, male Tettigoniidae with smaller spermatophores have the benefit of being able to mate two to three times per night, but have lower chances of being selected by females. Even in times of nutritional stress, male Tettigoniidae continue to invest nutrients within their spermatophores. In some species, the cost of creating the spermatophore is low, but even in those which it is not low, it is still not beneficial to reduce the quality of the spermatophore, as it would lead to lower reproductive selection and success. This low reproductive success is attributed to some Tettigoniidae species in which the spermatophylax that the female receives as a food gift from the male during copulation increases the reproductive output of the reproduction attempt. However, in other cases, the female receives few, if any, benefits.<ref>{{cite journal |last1=Jia |first1=Zhiyun |last2=Jiang |first2=Zhigang |last3=Sakaluk |first3=Scott |title=Nutritional condition influences investment by male katydids in nuptial food gifts |journal=Ecological Entomology |date=2000 |volume=25 |issue=1|pages=115–118|doi=10.1046/j.1365-2311.2000.00239.x|bibcode=2000EcoEn..25..115J |s2cid=85677289 }}</ref>

The reproductive behavior of bush crickets has been studied in great depth. Studies <!-- conducted in 2010 at the University of Derby by Karim Vahed, Darren Parker and James Gilbert --> found that the tuberous bush cricket (''[[Platycleis affinis]]'') has the largest testes in proportion to body mass of any animal recorded. They account for 14% of the insect's body mass and are thought to enable a fast remating rate.<ref>{{cite journal |doi=10.1098/rsbl.2010.0840 |title=Larger testes are associated with a higher level of polyandry, but a smaller ejaculate volume, across bushcricket species (Tettigoniidae) |year=2010 |last1=Vahed |first1=K. |last2=Parker |first2=D.
