Tree crickets sing late into the fall months in northern states.  While viewing this page, you can hear the three types of calls made by male tree crickets:  continuous trilling, intermittent bursts of trills, and chirping.

This male Forbes' tree cricket has striking black limbs -- and a very dark metanotal gland.

This male Forbes' tree cricket has dark black distal limbs, but his femur is green.  The metanotal gland is dark, but not as dark as that of the tree cricket in the photo above.  (One hind leg is missing on this male-- not uncommon in tree crickets).

This male Forbes' tree cricket has green limbs, and a very pale metanotal gland.   Forbes' males and Black-horned males are often difficult to tell apart.  The can be ID'd by the pulse rate of their song - especially in hotter temperatures.  The antennal markings on the first two segments of the antennae are very similar for these two species.  One difference is that male Forbes' tree crickets almost always have a dark strip on the top of the head into the pronotum.

This male Pine tree cricket has reddish brown limbs, as well as a reddish brown metanotal gland.  In addition, the eyes of Pine tree crickets are often pink -- which happens to be the internal color of this male's metanotal gland.  (Future observations will hopefully reveal whether Pine tree crickets ONLY have pink areas inside the metanotal glands.  In addition, one spermatophore observed on a female Pine tree cricket was pink.)

This male Walker's tree cricket has raised his wings to prepare to sing - exposing his metanotal gland.

This male Snowy tree cricket has positioned himself between leaves to sing.  This is a common strategy used by males to increase the surface area of their wings -- and thus amplify their song. The are using the leaves as a baffle.  The Snowy tree cricket makes musical chirps rather than trilling.

This view of a male Snowy tree cricket shows the white colored metanotal gland.  Here again, this male has positioned himself at a natural gap in the leaf -- and attempts to fill the gap with his wings in order to amplify his song.

This Snowy tree cricket is making the fast chirping sounds you hear while viewing this page.

 This is a male Narrow-winged tree cricket.  He was actually hanging upside down while singing, but the photo is inverted for easier viewing.   Males of this species, like their name implies, have visibly  narrower wings than other species.

This male Narrow-winged tree cricket has positioned himself on this leaf to increase the surface area of his wings, thus amplifying his song.

 Four-spotted tree crickets are generally found closer to the ground than other species.  This male was perched on a plant in a large field -- about 12 inches off the ground.  This Four-spotted tree cricket song was very loud since were no shrubs or bushes impeding the sound waves.

This is the same male Four-spotted tree cricket with a view from above.  The sound was diminished, however, since sound waves from moving wings travels to the front and back of the wing surface -- not to the sides or above.

This Four-spotted tree cricket is making the rapid continuous trilling sound that you hear while viewing this page.

This is a male Two-spotted tree cricket.  This species often chews holes in leaves -- producing an opening that is an exact fit for their opened wings.  This male's head is protruding through the whole to the topside of this leaf.  We are looking at the back of his wings, his abdomen and two setsof legs.  His front legs are gripping the top of the leaf.

This view shows a male's head on the other side of a leaf.  You can see the hole he has chewed in this leaf.  When he trills, his wings lift and cover the hole.

This male Two-spotted tree cricket is making the mournful
intermittent trilling sound that you hear while viewing this page.
