PLATE, LAV a7 
Cicada Spumaria is not only common in this country, but is abun. 
dant in every part of Europe. It frequents moft plants, but thofe 
efpecially which exhale much moifture. The food of the larva ap= 
pears entirely of the vegetable kind, and confifts, perhaps, for the moft 
Part, of the fuperabundant fluids which all plants tranfpire, 
“ The Cuckxow-Sprr, or Frotu-WorM, is often found hid in 
that frothy matter which we find on the furface of plants. It has an 
oblong, obtufe body; and a large head, with {mall eyes. The ex- 
ternal Wings, for it hath four, are of a dufky brown colour, marked 
with two white {pots: the head-is-black.’ ‘The {pume in which it is 
found wallowing, is ll of its own formation, and very much refembles 
frothy {pittle. It proceeds from the vent of the animal, and_other 
Parts of the body ; and, if it be Wiped away, a new quantity will be* 
quickly feen ejeCted from the little animal's body. Within this {pume, 
it is feen in time to acquire four tubercles on its back, wherein the 
Wings are enclofed; thefe burfting, from a reptile it becomes a wing~ 
€danimal.” Adams, 
The colour of the winged Infeé is found to vary from a deep cho- 
colate, toa very pale brown. It is taken in July and Auguft. 
It rarely ufes its wings for flight, as the hiad legs are formed for 
leaping ; atfone effort it will frequently bound to the diflance of two 
8r three yards.
