69.008 (1982) Narrow-bordered Bee Hawk-moth Hemaris tityus (Linnaeus, 1758)

Resident. Rare.
UK BAP Priority Species.
Flight period

Lennon (1860) stated he had caught four around Dumfries, and by (1863) had found it not common, but had records for Dalskairth and Lochaber in the Mabie Forest (VC73). Gordon (1913) found it not uncommon, but that it was usually at Rhododendron flowers, from the 5th to the 18th June 1899. He also recorded several at Loch Elrig, Mochrum, and Sunny Braes, Corsemalzie, in late June 1898.
Although he recorded it under the old name of bombyliformis, he also stated 'narrow border', there being at the time confusion between the two species, Broad-bordered and Narrow-bordered, which had both used the same scientific name over the years.
Sir Arthur Duncan  had found three specimens at Tynron during late May early June 1946, three at National Museums Scotland. Further records were in 1935 and 1939 at Whauphill and Whithorn. Derek Ratcliffe on one of his rambles through southern Scotland had found it at Craigdarroch Wood (VC72) and Castramon Wood (VC73) in 1961. Again, two records in one year, 1978, one in the Lockerbie area, the other on the Loch Stroan railway cutting on 14th June.
In 2004 one was at Kirkmabreck Burn, Carsluith, on 22nd June.
Life cycle
Overwinters as a pupa. Larvae are present from mid-June to mid-August in a flimsy cocoon in plant debris, just below the surface.
Larval foodplants
Larvae feed on Devil's-bit Scabious (sometimes other scabious).
Care is needed to separate from Broad-Bordered Bee Hawkmoth.
Unimproved, often damp, grassland where it feeds at flowers such as Bugle and Bird's-foot Trefoil.
Recorders' notes
This moth is best found late morning and early afternoon when it is active in sunshine.
