This nice post on Azur Fox motivated me yesterday to make these bugs. They could be pendants or brooches. All I use was:
for dragonfly/vespa - studs, wire, strange silver object I've found, metal beads, copper elements I've bought (for wings), ant - buttons, studs and wire, scorpion - vintage ring, wire, screw nuts and metal beads.
I have to admit that I was inspired by Hanna Bernhard works.
they are about 3-4 cm long
