More example sentences
  • There aren't very large numbers of macro moths, just a few noctuids, some small pyralids, and a handful of geometrids.
  • Identification of most caterpillars was problematic so ecological groupings were used to create five subgroups: a bract-associated morphospecies, foliage-associated taxa, geometrids, and a lichen-associated morphospecies.
