Yellow-headed Scoliid
A large dark wasp with prominent yellow head markings and smoky wings. It is a parasitoid of large scarab beetle grubs in tropical Asian soils.
Did You Know?
It has been used in biological control programs against coconut rhinoceros beetles threatening palm plantations.
Corn Flea Beetle
A very small, shiny black to bronze flea beetle with a compact, oval body. It vectors Stewart's wilt bacterium, making it both a direct and indirect pest of sweet corn.
Did You Know?
The severity of Stewart's wilt in a given year can be predicted by winter temperatures, since cold winters reduce overwintering beetle populations.
