The Nackidow is a medium-sized member of the awrapnid family appearing in Pikmin: Planetary Evolution, within a cave known as Concrete Den. It ignores Pikmin, and only attacks leaders.

In Pikmin: Dual Worlds
The Nackidow is a medium sized member of the awrapnid family appearing in Pikmin: Dual Worlds. For the most part it ignores Pikmin, instead attacking Leaders. If it happens to ensnare any Pikmin, it will happily eat them, though it prefers to attack leaders, possibly due to the beacon on their helmets. The Nackidow will drop from above or jump on your squad from behind a corner, wrapping your squad up in the web it has stretched amongst it's legs and dragging the squad off elsewhere. Once at it's destination it will unwrap your squad, allowing it to eat your Pikmin and bite any Leaders. If you failed to defeat it prior to being wrapped up, here's your last chance to escape without any casualties. Elsewise, it will eat up to 5 Pikmin at a time or deal 1/16 damage to your Leader/s.

Charlie's Notes: These things got the drop even on me. I would take special care to scout out any dark corners or strange shadows before walking though with my squad. A few Rock Pikmin take care of it just fine, same as it's web-weaving relative, though!
