geometrid /dʒɪˈɒmɪtrɪd /noun EntomologyA moth of a large family (Geometridae), distinguished by having twig-like caterpillars (loopers) that move by looping and straightening the body. Also called geometer.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.
- All analysis is based on comparison of melanic and nonmelanic forms, without reference to genotype (the melanic forms in the two geometrids are dominant).
Origin Late 19th century: from modern Latin Geometridae (plural), from the genus name Geometra, from Greek geōmetrēs (see geometer). |
