Latrine Fly

A small fly that breeds in excrement and decaying organic matter in latrines and drains. It can cause urogenital myiasis when larvae enter the urinary tract.

💡

Did You Know?

Its flattened, spiny larvae are among the few fly species documented to cause urinary myiasis in humans.

Green Tortoise Beetle

A broadly oval, flattened beetle that is bright green in life, with transparent margins around the pronotum and elytra. It closely resembles a tiny green shield when viewed from above.

💡

Did You Know?

The green coloring fades rapidly after death, turning dull brown in preserved specimens, which is why museum collections do not reflect its living beauty.
