JNO. C. WILSON,

Fossil Insects in Amber

As no one has replied to Mr. Doria's letter in NATURE for February 25 (p. 392), I may say, in response to his inquiry, that I have heard in England a number of bees on a species of Tilia, at dusk, when it was probably much darker than the “very bright moonlight” referred to by Mr. Doria. It was too dark to watch them, but their “hum” was very audible, and on my dragging down a bough of the tree I saw one bee fly away. In Herman Müller's “Fertilisation of Flowers,” English translation, p. 67, it is stated that a social wasp (Apoica pallida) in Brazil seeks honey “only by night,” sitting still in its nest by day.
