The apparent primary pollinators of angraecoids seem to be hawk moths, family Sphingidae. Available evidence suggests that those hawk moths that feed, and pollinate, stereotypically receive the pollinaria on the compound eyes or the base of the proboscis.

An interesting read on this matter is found at http://www.geocities.com/pennypoint9/hawkmoth.html

There is little information in the scientific literature, but what was published is excellent quality. You should look for papers authored by L. A. Nilsson, during the 1980's. Of particular note is his 1985 paper: Nilsson, L.A., L. Jonsson, L. Rason, and E. Randrianjohany. 1985. Monophily and pollination mechanisms in Angraecum arachnites (Orchidaceae) in a guild of long-tongued hawk-moths (Sphingidae) in Madagascar. Bot. J. Linn. Soc., 26(1): 1-19.

Can anyone point me to a reference that indicates where exactly the pollinia of an angraecum attaches on a moth's body? Is it the proboscis of the moth or its head?

Thanks.
