Field observations of the hunting and nesting behaviour of Tachypompilus analis (Fabricius, 1781) (Pompilinae: Pompilini) were carried out by the author in the vicinity of his house in Hong Kong over several years. Behaviour on one particular nesting niche is described as well as the capture of a rare prey species. It was noted that although the species is known to excavate shallow depressions in soil as nesting sites, T. analis also chooses pre-existing cavities in masonry. Additionally, T. analis was observed to prey upon a web-fabricating spider (Agelenidae or Amaurobiidae), a clear departure from the usual wandering type preyed upon by the genus. This choice affects the normal hunting sequences possessed by the genus. From fragmentary observations I suggest that T.analis may have some level of behavioural plasticity, probably providing a net gain in parental investment.
