Entomology : with special reference to its biological and economic aspects . Foot of honey bee, Apis niel-lifera. c, c, claws; p, pulvillus;fi-t^, tarsal segments.— Caterpillar of Phlegethontius sexta. Natural size. ANATOMY AND PHYSIOLOGY 55 as in Stenohothrus and such other Acridiidse as stridulate byrubbing the femora against the tegmina. Legs of Larvae.^—Tlioracic legs, terminating in a singleclaw, are present in most larvae. Caterpillars have, in addi-tion, fleshy abdominal legs (Fig. 64) ending in a circlet ofhooks. Most caterpillars have five pairs of these legs (onabdominal segments 3, 4, 5, 6 and 10), but the rest vary inthis respect. Thus Lagoa has seven pairs (segments 2-7 and10) and Geometridae two (segments 6 and 10), while a fewcaterpillars {Tischcria, Limacodcs) have none. Larvae of Fig. 65.
