Spring Field Cricket

A black field cricket that overwinters as a late-instar nymph and matures in spring. Its early-season singing distinguishes it from the fall field cricket.

Did You Know?

It and the fall field cricket were long considered the same species until differences in life cycle timing revealed they are reproductively isolated.

Mercury Islands Tusked Weta

One of New Zealands rarest insects, found only on Middle Mercury Island. Males have curved tusks on their mandibles used in territorial combat with rivals.
