An interested female Tree Cricket is approaching a male below her.

The male turns around.

She quickly turns away. There are many other suitors she wants to check out….

Here’s a pair approaching each other ever so cautiously.

Here’s a male displaying with upraised wings for the female.

Unimpressed, she moves on. Is that pit right behind the males’s upright wings the metanotal gland? She doesn’t like his offering?

Maybe his metanotal gland has been depleted from previous matings?

Most of the females have rotund abdomens, ready to lay their eggs.

Look at the size of her abdomen! The straight brown shaft at the tip of her abdomen is probably her ovipositor.

The female suddenly curls her abdomen forward between her legs.


She’s feeding on something on her genitals. Aah, I think I know what is happening! The female must be freshly mated, and is finishing up the spermatophylax that has been gifted to her along with the spermatophore.
In the Ensifera (suborder including the crickets and katydids), males produce a spermatophore or capsule containing sperm to be transferred in entirety to the female’s spermatheca during copulation. The spermatophore is often surrounded by a jelly-like proteinaceous spermatophylax, a nutritious substance which is commonly eaten by the female, and thus functions as a nuptial food gift. The function of the spermatophylax is to cause the female to relinquish some of her control over the insemination process allowing full sperm transfer from the spermatophore into the female’s spermatheca.

The female takes a little time relishing the nuptial food gift from her mate.

Then she straightens up and moves away.

Here’s a pair mating! A female has climbed on the back of a displaying but silent male. They remain in this position for a while.
After the tree cricket male woos the female with song, she consents by climbing onto his back, where he maneuvers a tube from his ejaculatory apparatus into her reproductive tract. The spermatophore detaches from the male and empties sperm into the female. Male tree crickets have metanotal glands behind their wings that secrete a tasty substance. During sperm transfer, the female gorges herself on the gland secretions which help boost her reproductive success.

Then she quietly sidles down from his back…

The pair rests side-by-side for some time, while the male continues to keep his wings upright. What a sweet moment! Thank you, Tree Crickets for that magnificent show. I have never in my wildest dreams thought I would witness this precious moment, with just enough light to see and photograph the action.
On that note, I get up from the ground, dust myself off and put on my jacket. It is getting chilly and dark. Time to head home before my husband calls the search and rescue team.
