Bush crickets

Phaneroptera nigroantennata

Black-footed bush-cricket

Its legs turn black while the rest of its body ages from green to brown, and unlike most bush crickets, adults can live for more than a year.

Size19 to 23 mm body length
WhenJune to October

Nymphs and freshly matured adults of this bush cricket are green, but nearly all individuals turn brown within weeks, keeping only their black legs as a constant field mark among the pale green wings.

It lives along grassy forest edges and riverbanks, singing at night from vegetation, and unlike many katydids of similar size, adults are unusually long lived, some surviving for more than a year.
