Ujadani

Ujadani are very small, orange bugs that scuttle about in swarms of many. Upon closer examination, they appear to have tiny scuttling feet before their bulbous backs. The creatures can be attacked similarly to the way Pikmin attack rubble and nectar weed and doing so results in the insects releasing vast quantities of nectar and spray drops. Non-White Pikmin are affected by the poison the swarms release when attacked. The insects rarely attack, however, so it's possible to beat all insects without any non-White Pikmin being poisoned.

Pikmin: Infection in Progress
The Ujadani beetles return in Pikmin: Infection in Progress, and appear in most areas for environmental purposes. An exceptionally large amount of Ujadani beetles appear in Withering Terrace, and lesser swarms appear in Noxious Expanse, Polluted Creek, and Toxic Barrens. It should be noted that the Ujadani in Fungal Grotto have a slight luminosity to them. They are ignored by all creatures and even crawl onto them sometimes. Ujadani beetles cannot attack or be attacked in Pikmin: Infection in Progress.
