Trachypus
bee-hunting wasp
Trachypus is a Neotropical genus of digger wasps in the family Crabronidae, comprising 31 described species. Species are ground-nesting and may be solitary or communal. The genus is notable for its specialized predation on bees, with some species exhibiting narrow prey specialization on stingless bees (Meliponini). Trachypus species harbor symbiotic streptomycete bacteria in antennal glands, a trait shared with their close relative Philanthus.
Xyleborus affinis
sugarcane shot-hole borer
Xyleborus affinis is a highly widespread ambrosia beetle native to the American tropics, now found in tropical and subtropical regions worldwide. It cultivates symbiotic fungi in galleries bored into decaying wood, feeding exclusively on these fungal gardens. The species exhibits facultative eusociality with delayed dispersal of adult offspring, who assist with nest maintenance and brood care. Females are the dispersing sex and are strongly attracted to ethanol and specific host plant volatiles. Despite frequent association with declining trees, it primarily colonizes wood already in early decay rather than causing primary mortality.
