Vella americana
Vella americana is a large antlion species in the family Myrmeleontidae, notable for being among the largest antlions in North America with adult wingspans exceeding 100 mm. Unlike pit-digging antlions of the genus Myrmeleon, larvae of Vella bury themselves just below the soil surface and wait for prey. Two distinctive larval behaviors have been documented: 'surface travel,' where larvae move across exposed substrates to relocate, and 'sand-blast,' rapid expulsion of sand from the mouth to clear debris or excavate. Adults are frequently attracted to lights at night.
