Today, declines in the populations of bees and other pollinators, important contributors to environmental heath and biodiversity, have given rise to renewed calls for study such as the United States' "Pollinator Research Action Plan." In Ireland, only 122 species of hymenoptera had been documented prior to 1924. That year, naturalist Arthur Wilson Stelfox reported another 53 new species, increasing the known species in Ireland by almost half. Stelfox's subsequent collection of specimens in the years that followed documented more still. Please join us in the transcription of his field diary of his collection trips in 1936 and 1937 which range from the northwestern coast of Ireland to Kilkea Castle in the southeastern countryside.
