The Monster Hunter World Hornetaur is one of the more useful small creatures you'll come across on your adventure.
Like other small creatures not only do they have their own armour to craft, but they are also a key component in certain other monster armours, as well as being the subject of the game's many optional hunts and investigations.
Hornetaur locations in Monster Hunter World
Hornetaurs find their home in the Rotten Vale, the game's fourth location that you'll come across as you complete Assigned quests. You won't have a need for them until you visit here, so there's no need to unlock anything further.
Hornetaurs are best found in areas 3 and 4, which are on the western side of the upper level. They are large black bugs, which will approach and attack you when you get close.
Though they can knock you back, thankfully they aren't heavy damage dealers, and will go down with a few attacks of your chosen method of attack.
Before the arrival of the new expansion is a list of Monster Hunter World Iceborne beta dates and details on Monster Hunter World Iceborne weapon changes and types. Until then, it's worth scrubbing up on the base game. As well as our Monster Hunter World tips, our Monster Hunter World walkthrough and guide explains how Assigned missions, Expeditions and Investigations work, which will see you hunt Anjanath, Zorah Magdaros, Diablos, Odogaron, as well as Elder Dragons Kushala Daora, Teostra, Vaal Hazah, Xeno'Jiiva and Kirin, as well as the recently added Behemoth. If you are starting out, we recommend learning how to join friends and Squads in multiplayer, plus how to capture monsters and mount monsters. There's plenty of optional stuff, too - such as Grimalkynes and Doodles, helping unlock Plunderblade and Gajalaka quests.
Where to find Hornetaur Carapace and Hornetaur Innerwing
Depending on your weapon tree choice and which armour you are building (such as the popular Odogaron High Rank set) you may be asked to seek out two specific materials - the Hornetaur Carapace and Hornetaur Innerwing.
You will find these from the very same Hornetaur locations as above, except you must play in High Rank. So whether you go into the Rotten Vale on Expedition mode, or during another activity, they will give you these items upon carving.
Both seem equally as common, but since you are likely to completely destroy Hornetaurs upon defeat, it might take a couple of visits to get all the materials you need for your upgrades.
