NOTES ON THE EARLY STAGES OF XYLOTRECHUS ANNOSUS, Say
Published online by Cambridge University Press: 31 May 2012
Extract
In the mouth of April, 1880, I cut down a willow tree and cut it up into “sled-lengths,” when no traces of borers could be seen. Early in March of the following year, while cutting this wood for the stove, I found it to be infested with the larvæ of some species of longicorn beetle; I placed some of the sticks in one of my breeding cages where it remained undisturbed until the 7th of May following, when I found that nearly all the larvæ had assumed the pupa form. The next examination was made two weeks later, when nothing but perfect beetles were found. From this it would seem that this species requires only one year to complete its transformations.
