bees
No they do not.
Unfortunately, there are no swarms on HeartGold and SoulSilver, only on Diamond, Pearl and Platinum.
The secret bugs appear only in the Wistful Wild every 30 days, starting with the 31st day. They are small orange creatures that travel in swarms, but they have no Piklopedia entry. Not only are they a rare novelty, but Pikmin can attack them to release nectar, Ultra-Spicy Spray, and Ultra Bitter Spray in large quantities. Be careful, as the swarms can also release poison when they are attacked.
Many insects travel in swarms - including (but not limited to) bees, flies, grass-hoppers, locusts, moths & butterflies.
