04 OF THE SENSES OF 
they breed a female of the Lappit Moth, (Gastro- 
pacha Quercifolia,) and some other day flying 
species, to take her in a box with a gauze lid into 
the vicinity of the woods, where, if the weather be 
favourable, she never fails to attract a numerous train 
ef males, whose only business appears to be an 
incessant, rapid, and undulating flight in search of 
the females. One of these is no sooner discovered, 
than they become so much enamoured of their fair 
kinswoman, as absolutely to lose all fear for their 
own personal safety, which, at other times, is 
effectually secured by the reiterated evolutions of 
their strong and rapid wings. So fearless, indeed, 
have I beheld them on these occasions, as to climb 
up and down the sides of the cage which contained 
the dear object of their eager pursuit, in exactly the 
same manner as Honey Bees which have lost them- 
selves, climb up and down the glasses of a window.” 
After the butterflies, sphinges, and moths, have 
arrived at their perfect, or imago condition, their 
whole business seems to be the fulfilment of that 
universal law of nature, the reproduction of their 
kind. This is prettily told by Darwin, in the fol- 
lowing lines :— 
Ifence, when the morus,* in Italia’s lands, 
To spring’s warm leaves its timid leaf expands, 
The silkworm broods in countless tribes above 
Crop the green treasure, uninform’d of love 5
