Economic Importance

Caenodelphax teapae is a widespread pest in the Neotropics; transmits Urochloa hoja blanca virus (UHBV) in plantain signalgrass.


This genus was recently revised by Kennedy & Bartlett (2014).

Caenodelphax teapae is an extremely common (“weedy”) species throughout much of the moist tropics, including southern Florida.

Caenodelphax was historically (i.e., Fennah, 1965) a tropical genus, but it was redefined by Hamilton (2002) to be more inclusive, but subsequently revised by Kennedy and Bartlett (2014) to include only the type species (with C. philyra a junior synonym).

Caenodelphax species typically have pale, antennae contrasting with a dark body. Caenodelphax teapae has characteristically darkened wings (with a characteristic clear patch on the leading margin.  Females are characteristically paler. Segment X of the abdomen has short, stout processes that, in lateral view, are terminally serrulate.
