Melaloncha
''Melaloncha'' is a genus of phorid flies (Diptera: Phoridae) commonly referred to as "bee-killing flies". They are found almost exclusively in the Neotropical region, although there is one record from extreme southern Texas, United States. They are small flies, usually about in length. No true fossils are known, although there are some specimens in Colombian copal, of unknown (but likely relatively recent) age.
==Life history==
Species of ''Melaloncha'' are parasitoids of bees, especially stingless bees (Meliponini), but also introduced European honey bees (''Apis mellifera''), bumblebees (''Bombus''), and halictid bees (''Megalopta''). Some attack their hosts while flying, darting down to lay their eggs; others land, curl their ovipositor under their bodies and rush their hosts on foot (as in ''M. acoma'', see photo); a few carefully land on their host and stealthily inject their egg.
The flies can be attracted by spraying a mixture of honey and water on undergrowth to attract an aggregation of host bees. Frequently, they are found on palm tree flowers (again, with host bees), and sometimes they are encountered around bee nests.
