THREE RHYMING RIDDLES

1)
Drawn by artists since days of old,
But only seen when the weather is cold.

2)
Though blind I am, I lead the blind,
Whichever way they're so inclined.

3)
It wanders by on silent wing,
At dusk and at dawn too;
Add two letters and forth you'll bring
Someone who's close to you.

HINTS:
1. Drawn is a homograph.
2. "It" is an insect.

Answers:
