My dear Sir

I have received the enclosed moth from Queensland Australia under the name of Ophideres fullonica. The sender gives me a curious account of having caught large numbers with the proboscides deeply embedded in oranges.1 This interests me as bearing on some of my orchis work.2

Now will you have the kindness to tell me to what family the moth belongs, and more especially whether there is any English genus closely allied & with fairly large species. One of my sons has a moderate collection & I could get thus a proboscis for comparison, as that of Ophideres seems to me in my ignorance an extraordinary structure.3

Pray grant me this favour & believe me yours sincerely | Ch. Darwin

P.S The moth from which the proboscis has been removed need not of course be returned

The specimen of Ophideres fullonica (now Eudocima phalonia, the Pacific fruit-piercing moth) was sent by Anthelme Thozet; the account sent to CD has not been found but was an article from a Queensland newspaper (F. Darwin 1875b, p. 384). According to an account in the Queensland Times (6 April 1869, p. 3), Thozet’s discovery was first reported in the Rockhampton Bulletin and Central Queensland Advertiser in April 1869; no copy of the original report has been found. Discussion of the damage done by the moths was revived in the Queensland newspapers in May 1875 (Rockhampton Bulletin, 4 May 1875, p. 3).
2
CD added a reference to Ophideres fullonica in Orchids 2d ed., p. 40, as further evidence that moths and butterflies were capable of piercing the nectaries of orchids.
3
The moth collection probably belonged to Francis Darwin, who published an article on the structure of the proboscis of Ophideres fullonica in October 1875; he described it as like a toothed, three-sided bayonet or saw (F. Darwin 1875b).
