Dear Mrs. Maskelyne

I will forward your kind message to my daughter2 who is in N. Wales.—

Many years ago I was familiar with the plant in question, as it grew in my Father’s garden, & I have seen it studded with dead flies.—3 I have never had time to investigate the case, but believe that the slaughter of so many wretched flies is of not the least use to the plant; but that it requires for its fertilisation the visits of small Hymenoptera, which are not caught, as their proboscides are not enlarged at the end.—4

I beg leave to remain | Yours faithfully & obliged | Charles Darwin

Footnotes

Elizabeth Darwin or Henrietta Emma Litchfield. Story-Maskelyne’s message has not been found.
Robert Waring Darwin (1766–1848) lived in Shrewsbury. The plant was Apocynum androsaemifolium (fly-trap dogbane); see also Correspondence vol. 8, letter to Asa Gray, 26 November [1860], and Campbell 2012.
Hymenoptera: the order of bees, wasps, and ants. Many Diptera (true flies) have probosces with paired labella at the tip.

Summary

Explains that the plant is not consuming the flies, but that they die becasue they get stuck in the flowers when fertilising them.
