246 MINUTE MARVELS OF NATURE 



worthy of inspection. Fig. 166 shows some taken 

 from the familiar " woolly-bear " or larva of the 

 Tiger Moth ; and these, as the illustration shows, 



Fig. 165. Markings on wing of butterfly, 

 showing scales in situ 



are not just the simple hairs they seem, but are 

 beset with bristly fibrils along their length. Again 

 the hairs from the large humble bee (Fig. 167) 

 show that these branched hairs are not confined 

 to caterpillars, but are sometimes found on perfect 

 insects. And, as the scales of insects are but 

 modified hairs, the leg of the Tiger Moth shown at 

 Fig. 1 68 may be interesting as showing scales and 

 hairs growing together.
