Abstract
THE swarms of butterflies alluded to in NATURE, vol. xx. p. 183, have been observed in various localities of Switzerland—Lausanne, Merges, the foot of the Jura, &c. The passage lasted a long time, from one to four hours, on June 9; the species was Vanessa cardui. By comparing the hours and dates of the appearance in the various localities, I am convinced that it is simply due to the extraordinary local fecundity of this species, and not to a migration of butterflies from Africa or the shores of the Mediterranean, as various French and Swiss journals have supposed.
