The mimicry of vegetable by animal forms is here illustrated by figures of 

 some looping caterpillars, termed "Walking branches," and by that of a moth, 

 the Oak Lappet ( Gastropacha quercifolia), likened to a Walking Leaf. Above 

 the latter, fixed motionless to a branch of hawthorn, which it closely simulates, 

 is the caterpillar of the Brimstone Moth (Rumia cratcegata), the moth itself 

 appearing in flight above. On the left, another stick caterpillar that of the 

 Swallow-tail Moth (Ourapterix sambucaria), is attached to a branch of elder, 

 of which it affords a close copy in form, colour, and markings. A second 

 specimen of the same in its walking position forms an arch upon the branch 

 below.

 cluster of a Monday's swarm gathered round 

 one particular case of the entomologic collec-
