There are three ways to soften butterflies:
1. Natural softening method:
Add 100ml of water and drop 5-10 drops of stone carbonate solution into the drying container. Place the dried butterfly specimens packed in triangular paper bags on the partition board in the dryer. Multiple triangular paper bags can be placed at a time. Then cover the dryer and place it for 1-2 days, and the dried butterfly specimens can be soft again.
2. Water bath fumigation method:
Place the dried butterfly specimens packed in triangular paper bags in a small bowl. You can place multiple such triangular paper bags at a time, cover them with a small plate, then place them in a soup pot with a small amount of water, cover them, slowly heat them with slow fire until the water boils, and steam them for 5-10 minutes. Then the dried butterfly specimens can be soft again.
3. Injection boiling water method:
During field activities, we usually bring hot water. At this time, we can prepare a 5ml medical syringe (with needle) for standby. When a dried butterfly specimen needs to be softened, a medical syringe can be used to inject a little hot water into the chest of the dried butterfly specimen, and the dried butterfly specimen will be softened and used slowly.
