Apple Maggot Fly

A fruit fly pest whose larvae tunnel through apple flesh causing brown trails. It is a textbook example of sympatric speciation by host plant shifting.

💡

Did You Know?

It shifted from native hawthorn to introduced apple trees in under 200 years, creating genetically distinct races.

Indian Sand Fly

A tiny, hairy fly with a distinctive humpbacked appearance and large, upturned wings held erect at rest. It is the primary vector of visceral leishmaniasis (kala-azar) in the Indian subcontinent.

💡

Did You Know?

Indoor residual spraying with DDT once nearly eliminated kala-azar from India, but the disease resurged after spraying campaigns ended.
