Here's another fun themed costume idea for a group of friends or family -- how about going as a bunch of insects? Here are some costume ideas for bugging out this Halloween.
This is a funny green mask of a Praying Mantis. There are over 2000 species in the mantis family, with a lot of similar-looking types, so this is hard to pin down to species. Match this with a lime-green outfit and hold your hands in a prayer position -- you can't go wrong. You could also go for the full costume with this choice.
Here's another costume that comes complete with extra legs. This outfit comes with the top that has a hood and extra spider legs. You'll also get an abdomen piece and knee and ankle accessories to pair with your own black pants, tights, or leggings for the seventh and eighth spider legs. Spiders aren't technically insects but they go well with this themed group costume.
Speaking of creatures that aren't insects, this mask of a banana slug goes well with an insect group costume even if it isn't technically correct. Pair this realistic mask with a banana-colored outfit to complete the slimy look. Leave a trail of moisture behind you for added authenticity.
