APRIL.
In this Month a great Variety of Caterpillars and Chrysalides may be taken by the Method already described. The Banks about the Chelsea Water-Works and such-like Places are most likely to furnish the Chrysalides of the Hawk Tribe.
At the Roots of the Elm, Lime, Willow, and Poplar Trees, you will find in this Month a Variety of Aureliæ, which will produce their Flies in the May and June following.
Be now diligent to collect Caterpillars from all kinds of Growths, which, if taken Care of, will produce their Flies a few Months hence. Towards the End of this Month some Flies may be taken in the Day-time, and some Moths in the Evening.
