Pheropsophus aequinoctialis is a species of ground beetle from Yucatán and Central and South America that feeds as larvae on the eggs of mole crickets but as an adult is a generalist feeder.

[1] It has a similar colour pattern to the beetles Phaeoxantha bifasciata, P. klugii and Trichognathus marginipennis, and all these species probably form a Müllerian mimicry complex.

[1] Pheropsophus aequinoctialis adults are nocturnal, often hiding in groups during the day under stones, logs or clumps of grass, but emerging in the night to run along sandy trails or riverine beaches.

[2] The mole crickets' burrowing and the feeding by their adults and nymphs larvae cause significant damage to several grass species, including Paspalum notatum, Cynodon dactylon, Eremochloa ophiuroides, Stenotaphrum secundatum, Zoysia spp.

[1] The three instars (larval stages) which follow are white, with a cream head capsule, and darker colouration at the tips of the mouthparts.
