Ant crickets lives as an inquiline within ants' nests. M. pergandei is known to live with eleven ant species. This specialized way of life has led this insect and its relatives to evolve many morphological differences compared to other orthopterans, including complete absence of wings and hearing organs, and much reduced...

Under 5% of wildlife watchers report an Eastern Ant Cricket sighting in Washington on a given day, based on 106 verified sightings from GBIF citizen-science data. It is the 424th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Eastern Ant Cricket is recorded against all the insects logged in Washington (106 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
