JULY.

The first ten Days in this Month are the Time for taking the Purple Emperor-Butterfly in Comb Wood; and the Fields adjacent can furnish such a charming Variety of Moths and Butterflies, that I do not know any Place where an Aurelian can spend a Week with more Satisfaction and Assurance of Success. As soon as the Purple Emperor-Butterfly begins to grow bad, the Time comes on when the second Breed of the Swallow-tail Butterfly is quite fresh, as also the Great Tortoise-shell, Peacock Butterfly, &c. About the Middle of this Month you may find the Great Red Underwing and the Goat-Moth standing against the Willow-Trees which usually grow by the Sides of Ditches about the old Barge-House, Rotherhith, Vauxhall, and likewise in other Places. Seek also for the Caterpillars that produce the Great Elephant and Gold-Spot Moths: the most certain Places to find which, that I know of, are by the Sides of the Ditches in Rotherhith Marshes. The Caterpillars that produce the Elephant Moth feeds on the White Ladies Bedstraw, those of the Gold-Spot on the Great Water-Grass. I have taken the Gold-Spot Chrysalis and Caterpillar likewise in the low Grounds by Vauxhall in Surry.
