Identification
The horizontal black mark on the scape has a slightly upward stroke. The two black marks on the pedicle are touching (either they touch or are extremely close for this species). The pronotum has no black.



This photo below of a 4th stage instar has noticeable characteristics which might be helpful in IDing instars of this species: note the dark straw-colored antennae, the central fine stripe from the face to the distal abdomen, the golden colored proximal limb joints, the thick 'squiggly' white markings on the sides of the abdomen and most notably - all those tiny black dots on the limbs and cerci.
Range
As of 1/2009, the SINA range map shows occurence to include the area from Washington south to California then east to Mississippi then northeast to Ohio and West Viginia then west back to Washington (excluding Michigan and Wisconsin.) County records were recorded in the tri-state junction area of New York, New Jersey and Pennsylvania. Another county record was recorded at the midpoint state line between Alabama and Georgia. Two additional county records were recorded in northern Florida. Also included is British Columbia, Alberta, Saskatchewan and Manitoba.
Habitat
Not documented as occuring in trees. Found on a variety of plants -- of varying heights. Not strictly a prairie dweller.
Life Cycle
Undergo a paurometabolous development (Gradual Metamorphosis). Nymphs resemble small adults and gradually develop external wing buds. They live in the same habitat as adults, typically taking the same food.
Remarks
A great source for 'everything you ever wanted to know about tree crickets' is an article written in May 1915 by Bentley B. Fulton in a Technical Bulletin for the New York Agricultural Experiment Station. The Tree Crickets of New York: Life History and Bionomics
