-nail polish remover or rubbing alcohol
Clean jars. I would have used plastic had I had them.
I don't recommend this brand, but it was given to me free from someone who didn't need it anymore. Any brand will do.
Pour into jars and let it dry 24 to 48 hours. Make more if you need to it won't ruin the outcome.
Add your remover or alcohol. About a tablespoon. Let it seep in and cover jar with lid immediately.
Find bugs, pop in jar. The will be asphyxiated and then they can be laid out in a couple of hours on a styro foam card and pinned. Do it sooner than later so that the wings etc are easy to maneuver.
Don't forget to have a classification book on hand. Yeah, I need to get one of those...
I'll post pics of finished jars later today after the girlies have had a chance to do up the lids with sequined bugs. Hey were girls we need to pretty it up a bit!
