Panama appears to be the northern limit of the range of this species. Mr. Champion 
sometimes found four or five specimens together on tree-trunks in the forest, which on 
being approached would immediately retreat to another tree, but always upward and 
more out of reach. “The flight is peculiar and different from that of any other insect 
observed, being spiral and perpendicular, generally from tree to tree; and one kind of 
tree being alone frequented, the trunk of which is covered with long sharp spines, 
between which the insect rests, thus adding to the difficulty of its capture.”

The proper choice of the above names is somewhat perplexing. Spinola first 
proposed that of Cladodiptera, for which Amyot and Serville subsequently substituted 
that of Cladypha on the ground that the name Cladodiptera was wrong in construction 
and should be Cladoptera, which, however, had been already used by one of them in 
Orthoptera. Prof. Westwood afterwards showed that this was again an error, as 
Cladoxerus was the name used by Serville, and not Cladoptera; and he, retaining 
Spinola’s name, “but altering its termination,” again makes a proposition that the 
name should be Cladopteryx. Under these circumstances I follow Stal in adopting 
the word Cladypha, which was the first new name proposed when a change became 
necessary. 
Walker elucidated the question by describing some species as belonging to the genus 
Poiocera, afterwards correctly recognizing Spinola’s genus and describing a species as a 
Cladodiptera ; and subsequently describing another species under a new genus, Diacira, 
a name almost simultaneously proposed by Stal for another genus of Homoptera.
