Lateral scale: one of the lateral processes of the ovipositor in Cynipidae, lying within and below the a.n.a.l scale.
Lateral s.p.a.ce: in slug caterpillars is the area on each side of the body between the subdorsal and lateral ridges.
Lateral sutures: of the thorax in Odonata, are situated on the sides of thorax, the first separating the metepisternum from the mesepimeron; the second separating the metepisternum from the metepimeron; the first more or less obsolete in the Anisoptera.
Lateral tubercle: lateral on thoracic and abdominal segments of caterpillars: it is 3 of the abdomen, 2a of thorax: constant (Dyar).

Laterostigmatal: situated on the side, immediately above the spiracle.
Lateroventral: the point of junction of sternum and pleurum.
Latero-ventral metathoracic carina: in Odonata; forms the dividing line between the metepimera and the metasternum.
