Introduction

All agonistic behaviour, be it for resources, territory or a mate has to be weighed against potential injury and metabolical cost of the display \cite{Maynard_Smith_1974}. As a result, agonistic behaviours are more likely to be displayed between individuals of similar mass, or social standing, due to individuals not being able to predict the outcome of the competition. However, as the value, or scarcity of the resource increases so does the frequency of agonistic displays between asymmetric pairs \cite{Injaian2015}. Increased frequency of agonistic displays in the presence of females is common in the Gryllidae family \cite{Adamo1995,Tachon1999}.  \cite{Rillich2011} This is likely because agonistic displays in field crickets is often an indicator of reproductive success, as winners are believed to have greater resource holding potential \cite{Stevenson2012}. Previous studies have shown agnostic displays escalate in a linear manner, though they can de-escalate. Usual indicators of high-level agnostic displays are a similar mass of crickets. 
Previous studies have examined the role female presence plays in agonistic displays in the field cricket. \cite{Montroy_2016} displayed a significant increase in male aggression and subsequent agonistic escalation in Gryllus assimilis in the presence of a female audience, although was unable to determine whether the cause was olfactory, visual or auditory.  EXAMPLE B INDICATES Y.
