00:00If you've been swatting away sweat bees, here's a surprise.
00:03They may not be bees at all.
00:05They could be hoverflies, insects that look like bees, but don't bite or sting.
00:10So why won't they leave you alone?
00:13Some are drawn to moisture and salt in your sweat.
00:16That makes you a tempting stop during their flight.
00:19Weather affects their activity too.
00:21Warmer conditions generally get them moving,
00:22while cooler temperatures slow them down.
00:24And these persistent visitors also pull their weight in the garden.
00:28Adults help pollinate flowers while their larvae and many species feast on aphids of other plant pests.
00:34To tell them apart, look for large eyes, short antenna, and two wings.
00:39Bees have four.
00:40Those uninvited visitors may be helping your garden, even if they're testing your patience.
