These stick insects are commonly known as BUDWING STICK INSECTS or RED WINGED STICK INSECTS and in the wild they can be found in the rainforests of Thailand.
They get their common name of 'budwing' stick insect because of their beautiful little wings which are highly patterned in pinks, oranges, yellows and browns as you can see below:
Their other common name of 'red winged' stick insect comes from the fact that underneath this outer 'bud' wing surface they have vivid crimson red coloured wings which are used to startle predators if they feel threatened. As you can see below this colour really is quite striking!!

This species is hugely popular with the many children they meet because they are very easy to handle, having only tiny tarsal (foot) claws which feel sticky rather than scratchy and no spines on their body unlike many of my other Phasmids!
