Trachelissa maculicollis (Audinet-Serville, 1834)

( Figs. 7, 8 )

This is the first published record for this locally common species in Bolivia. The adults are attracted to the nectaries of flowering Calliandra haematocephala Hassek (MIMOSACEAE) during the months of August and September and are most active from 09:30-11:00 am (when pairs were seen mating) and 17:30-18:30 pm. Adults appear to be attracted to clumps of deformed fruiting bodies, when present, as many individuals have been seen to collect in them. In one of these an unusual melanic specimen ( Fig. 8 ) was collected.

Although C. haematocephala has been introduced into many parts of the world, Bolivia is the only country where this shrub is known to occur in the wild (Nee, unpub.). It would be interesting to know whether or not this species has been found regularly on any other plant species in South America.
