Tree crickets display a variety of interesting behaviors. Most of what is offered on this page is from direct observations of tree crickets I have encountered or raised.
This Narrow-winged tree cricket is eating commercial cricket food powder. This little creature is almost cat-like in the manner it is eating.
This male is scouting his surroundings before literally taking a 'flying leap' -- tree crickets initially leap and use their wings to guide them.
This male Neoxabea bipunctata extends his forewings and hindwings before taking a short flight.
This is a female O. celerinictus and a male O. walkeri. They were placed in the same vase to rule out the male being O. celerinictus. The female spent over a minute touching the male with her antennae -- and seemed to be enticing him to sing and offer her access to his metanotal gland. He did not, however, seem interested in her. After a while, as if to tell her "Go away, I'm not your kind" -- he gave a short trill. She in turn, seemed to realize by his song that he was not her species -- turned around -- and paid him no further attention.
This female Tamarack tree cricket uses her forearm to groom an antenna.
