Hand netting was done from scaffolds erected (typically 8–
12 m high) into the canopy. Insects were collected from 08:00
to 14:00 h each day, coinciding with the most receptive period
of teak flowers (Tangmitcharoen and Owens, 1997). Collected
insects were killed in a glass container containing cotton
saturated with ethyl acetate (CH3COOC2H5). All collected
specimens were preserved in 70% ethanol for later sorting.
