Katydids and crickets can be separated from grasshoppers by their long antennae (longer than body). Immature orthopterans do not pass through a pupal stage and look much like smaller versions of the adults with stubby wings.

Orthoptera (grasshoppers, katydids, crickets) of Ojibway

Grasshopper, crickets and katydids belong to the insect order Orthoptera (meaning "straight-wing") and are best known for their powerful hind limbs and ability to jump. There is a single generation per year with adults most commonly present in late summer. A few species overwinter as nymphs and the adults appear in spring or early summer.

There are 49 species recorded in the Ojibway area. Species such as Short-winged Green Grasshopper, Scudder's Short-winged Grasshopper and Say's Bush Cricket have affinities to prairie habitat while others such as Walsh's Grasshopper, Davis's Tree Cricket, Two-spotted Tree Crickets and Eastern Ant Cricket are southern species rarely recorded in Canada.

Many katydids and crickets can be more easily identified by song than by sight. Many species are accomphished singers and the park is alive with song on warm summer and early autumn evenings. The Snowy Tree Cricket is well known as the "temperature cricket". Count the number of chirps in 13 seconds and add 40 to calculate the temperature (F.).
Here is a 13 second MP3 recording of Snowy Tree Cricket taken at Ojibway. What was the temperature?
