Green-legged Sawfly
An Australian pergid whose larvae feed gregariously on eucalyptus foliage. Heavy defoliation can stress and weaken young plantation trees.
Did You Know?
Larvae regurgitate a pungent eucalyptus-oil-based liquid as a chemical defense against birds.
Sunda Colugo Fly
A parasitoid wasp with a slender body, extremely long ovipositor, and distinctively bicolored black and orange body. It drills into wood to parasitize beetle larvae hidden inside.
Did You Know?
The female's ovipositor can be twice the length of her body and she can detect beetle larvae hidden deep inside wood through vibrations.
