It is not really a animal friendly festival but every year at end of September or begin October there is the "Hercules (Kwang) Beetle Festival" in Pua in Nan province, North Thailand. The Hercules’s Beetle is a bug commonly found in Pua District, named ‘Fighter of the Mountains’ due to its fighting habits. The festival is aimed at conserving the local tradition, particularly Hercules’s Beetle fighting. During the festival are also shown other local community traditions like silverware production and local woven textile from nearby hill-tribe people.

Remark : I mention this festival because it is part of all festivals in Nan province. But personally I have never visited this festival as I think it is a kind of animal cruelty.September / October, exact days change per year.
