"The Search for the Rare Bikōchū Beetle" (超追尾力に赤丸も嫉妬!幻の微香虫を探せ, Chō-tsuibiryoku ni Akamaru mo shitto! Maboroshi no Bikōchū o Sagase) is episode 148 of the original Naruto anime.


Hinata, Shino and Kiba visit Kurenai Yūhi at the hospital and Hinata faints after getting too close to Naruto who was frustrated by Mizuki's inability to lead him to either Sasuke or Orochimaru. Naruto began pestering Tsunade to allow him to go look for him. Hinata sympathised with Naruto, and suggested trying to find a way to help him. Shino commented that a bikōchū, a very rare insect, would be able to track down Sasuke if it smelled his scent. As Kurenai was hospitalised for injuries that she had suffered during the prison break, Shino was tasked with leading Team 8 to find the bikōchū, and Naruto joined with them as the fourth member. It was also revealed that Hinata was practising a new defensive technique, and had nearly mastered it, and was seen training naked at a waterfall by Naruto at night, though he did not recognise her. The next morning Naruto told Kiba about the "ultra-pretty" girl he saw, embarrassing Hinata greatly. As they arrived at the location where the bikōchū is, they were unaware that the enemy group were also searching the bikōchū.
