Oecanthus nigricornis

Oecanthus nigricornis is a "common tree cricket" in the subfamily Oecanthinae ("tree crickets").[1][2] A common name for O. nigricornis is black-horned tree cricket.[3] It is found in North America.[2]

Black-horned tree cricket bats away a hover bee (could have been a parasite or predator) with its antenna (replayed in slow speed). Later a cricket sings.

Courtship feeding

[edit]

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]
