THE JOINTED ANIMALS 



V 



during July and August. The fore-wings are dull ochre brown, with two oblique 

 transverse brown bars. The eggs are laid by the female in the late summer in a 

 firmly attached ring round some small twigs as shown in the illustration. The 



larvae hatch in the spring 

 following, and are brown 

 with blue, white, red, and 

 yellow longitudinal 

 stripes; all feed on the 

 leaves of the pear and 

 other fruit trees, and spin 

 a long sulphurous yellow 

 cocoon among the leaves. 



Family 

 L TMA N TRIIDsE, 



LACKEY MOTH. 



Perfect insect, eggs, larvae, and cocoon. 



This group includes 

 a number of moths in 

 which the males have 

 the antennas strongly 



pectinated, while in the case of the genus Orgyia the female is wingless. None 

 possess a proboscis. The larvae are hairy, and clothed with long thick tufts, 

 springing in some places from wart-like prominences. The hairs of the larvae are 

 woven into the cocoon, and if they come in contact with the skin cause great 

 irritation. In this family are included some well-known British moths, such as the 

 vaporer (Orgyia antiqua), the pale tussock (Dasychira pudibunda} , the black 

 arches (Lymantria monacka), the gold tail and brown tail, the satin moth, and 

 many others. In the gypsy moth ( Ocneria 

 dispar) the wings of the male are smoky 

 black, while those of the female are gray; 

 the appearance of the two sexes being very 

 different indeed. The larvae feed on various 

 trees, and though very rare in England are 

 sometimes so abundant on the Continent as 

 to prove very destructive to all kinds of 

 trees and herbage; stripping even maize and 

 millet fields, orchard, and vegetable produce. HERMAPHRODITE OYPSY MOTH. 



The cocoon is formed in a few folded leaves spun together with silk or in 

 a crevice in the bark. The single figure represents an hermaphrodite specimen 

 of this insect. Its wings, antennae, and the dark half of the thorax and abdomen 

 on the left side are of the coloring and form peculiar to the male, while those 

 on the right resemble the form peculiar to the female. The illustration on 

 p. 3071 illustrates the stages in the development of the black arches moth, 

 which is not altogether abundant in England but much more commonly met
