Black-horned tree cricket bats away a hover fly with its antenna (replayed in slow speed). Later a cricket sings.

Courtship feeding

Bell 1979 finds courtship feeding goes into increased fecundity, however Arnold and Duvall 1994 finds quantity to not be the selection criterion: Female choice has evolved to prefer mates who give the highest value nuptial gift, disregarding quantity. Variation in quality between gifts also plays a role. [4]
