Lobus: of maxilla = galea; q.v.
Locomotion: organs of, are legs and wings.
Longicorn -ia: having the antennae as long or longer than the body; specifically the Cerambycid beetles.
Longitudinal: in the direction of the long axis.
Longitudinal veins: are those that extend lengthwise through the wing either directly from base or as branches of one that does start there: they are named or numbered, and differently in the different orders.
Loop: applied to that structure at base of innerside of primaries into which the frenulum of male moths is fitted: see retinaculum.
Looper: applied to geometrid and other caterpillars in which some or all the middle abdominal legs are wanting and which move by bringing tail to thorax and forming a loop of the intervening segments.
Lora: the chitinous bands connecting the submentum with the cardo of maxilla (Comst.): the submentum: small cords upon which the base of the proboscis is seated (Say): the anterior part of the genae at the edge of the mouth: the corneous processes to which the muscles flexing the mouth in certain Diptera are attached, and in that sense the palpifer of the maxilla: in Homoptera, the small sclerite at side of clypeus and front, extending laterally to the genae.
Lorum: in bees: the angular piece upon which the sub-mentum rests.
Lower austral zone: occupies southern part of United States from Chesapeake Bay to the great interior valley of California. Is interrupted by the continental divide in eastern Arizona and west New Mexico and divided according to conditions of humidity into an eastern or Austroriparian and western or lower Sonoran area.
