Arctic Sawfly
A small, dark sawfly associated with willows in Arctic and subarctic regions. Females use their saw-like ovipositor to cut slits in willow leaves and stems for egg-laying. Larvae resemble caterpillars and feed openly on leaves.
Did You Know?
Arctic sawfly larvae can produce silk pads to anchor themselves to willow leaves during strong tundra winds.
Sugarcane Woolly Aphid
A small aphid covered in white woolly wax secretions that forms dense colonies on the undersides of sugarcane leaves. Heavy infestations reduce cane juice quality and sugar recovery in mills.
Did You Know?
A major outbreak of this pest devastated the Indian sugarcane crop in 2002-2004 before biological control with parasitoid wasps brought it under control.
