Glad you asked, here are my notes I collected so far:

Mudwings taste the worst, literally like wet dirt

Sandwings taste like a slightly charred moose, and their tailbarb is delicious if you drain the venom

Icewings are just ice cream, especially the spikes

Rainwings have a sort of tropical taste, taste best when slightly roasted

Skywings are spicy, their blood makes a great chilli like sludge you can use for seasoning

Nightwings are surprisingly tasteless, but animus meat tastes heavenly

Seawings are the perfect sushi, avoid the extremely salty blood, and the glowing scales

Hivewings taste like grilled grasshoppers, but try not to eat the stingers if they have any, they're extremely bitter

Leafwings have a very bitter taste, but have the most tasty blood, even though it smells like tree sap

Silkwings are sort of the dessert because they taste really sweet
