How Long Do Preserved Butterflies & Insects Last?
Preserved butterflies, moths and other insects can last for many years — and potentially decades — when they are properly prepared, protected and displayed in the right conditions.
Unlike living material that quickly decomposes, professionally prepared insect specimens are dried and preserved before being mounted. Once protected inside a frame or display, very little ongoing maintenance is required.
However, there are a few things that can affect how well a specimen ages.
Can preserved butterflies last forever?
No natural specimen can be guaranteed to last forever, but properly preserved butterflies and insects can remain in excellent condition for a very long time.
In fact, natural history museums around the world hold insect specimens that are well over 100 years old.
The biggest difference is how the specimen is stored and displayed.
For a framed insect in your home, protecting it from sunlight, moisture, physical damage and insect pests will give it the best chance of remaining beautiful for years to come.
Does sunlight fade butterfly wings?
Yes. Prolonged exposure to direct sunlight can cause the colours of butterflies, moths and other insects to fade over time.
Butterfly and moth wings are covered in microscopic scales that create their incredible colours and patterns. These can be affected by prolonged UV exposure.
You don't need to keep your collection in a dark room — simply avoid hanging framed specimens somewhere that receives strong direct sunlight for hours each day.
Does humidity damage preserved insects?
High humidity and moisture aren't ideal for preserved specimens.
Keeping your framed insects in a normal, dry indoor environment helps protect them from deterioration and mould.
Bathrooms, very damp rooms and areas exposed to frequent condensation are best avoided.
Can bugs damage preserved insect collections?
Although it sounds strange, preserved insects can themselves be vulnerable to other insects.
Tiny museum pests such as dermestid beetles can feed on dried natural materials. This is one reason keeping specimens properly enclosed inside their frames or displays is important.
If you collect natural history specimens, it's also worth occasionally checking your collection for anything unusual inside the display.
Do you need to clean preserved butterflies?
The specimen itself generally shouldn't need cleaning when it's protected inside a frame.
Butterfly wings, antennae and legs can be extremely delicate, so touching or attempting to clean the actual insect can cause damage.
Instead, simply clean and dust the outside of the frame and glass when necessary.
How can I make my framed insects last longer?
The basic rules are surprisingly simple:
- Keep them away from prolonged direct sunlight.
- Avoid excessive humidity and moisture.
- Keep the specimen enclosed and protected.
- Avoid touching the actual insect.
- Keep frames away from strong heat sources.
- Occasionally inspect your collection for signs of pests.
Following these basic precautions can help keep a preserved insect collection looking beautiful for many years.
