About me + FAQ

Welcome to my website!  Allow me to introduce myself – lately I’ve been recieving a lot of questions, which is why I decided to add some information about myself on this website aswell.


1. Where do you get your livestock?
On the internet multiple communities and distributors can be found. One particulary useful website is http://www.actias.de which has an international marketplace on which multiple species are offered per day. Other than that commercial webstores can be found online, like http://www.wwb.co.uk/ (world wide butterflies). Making friends with hobbyists is also an important point – for they may have eggs for sale! Other than this I have many more private sources. Wild collectors, butterfly farms.. you name it!

2. What do you do with dead specimens?
Since there is demand for my dead lepidopterans, I usually sell or trade them to collectors. Since I prefer to breed live insects I don’t have need for the dead ones – however one downside of breeding is that you will need to keep them alive, and as butterflies and moths age their wings will tear. So I rarely have good quality specimens since most of them die  of old age.

3. Is it an expensive hobby?
It is as expensive as you allow it to be. Some very commonly bred species are very easy and cheap. Like the Samia ricini (eri silkmoth) or Arctia caja (garden tiger moth) and many of the common native cabbage whites (Pieris sp.) are commonly offered at low prices and very easy to breed and don’t need a lot of  equipment. Sometimes these species are even offered for free! And they can be easily reared and bred in plastic containers or net cages.

The price range will exponentially increase with the rarity and difficulty of the species  you aim to rear. For example the Graellsia isabellae (Stained glass moth) or Argema mittrei (Comet moth) are examples of species that are a bit more on the expensive side. The most expensive are species that are rare to obtain, endemics  or protected by CITES, for which prices may range to over 20 euro per pupa! Such extremes are rare and may include species as Actias chapae, Ornithoptera sp., Coscinocera hercules and more. However for a beginner this will be a cheap hobby.

 4. Do you release captive insects?
No. I keep non-native (exotic) species, releasing them would be highly irresponsible.  Even if I breed native species, releasing them could still have a negative impact on the wild population for captive insects may carry negative/unfavorable traits that would have been removed due to natural selection in the wild. I’ve been asked this question more times than I’m comfortable with: despite their pretty colours, exotic species are not welcome in our ecosystem. They can do serious damage to native wildlife. If you want to help sustain the populations of butterflies and  moths in the wild, the best course of action would be to help spread their host plants! Plant host and nectar plants in your garden. They are beneficial to the species, whereas releasing captive insects could have a negative impact.

 5. Do you sell livestock? 
Sometimes. But when I do, I usually place offers on the marketplace on the forum of http://www.actias.de ! So I recommend taking a look there.

 About me
My name is Bart Coppens, 24 (male). I live in the Netherlands, and since I were young I’ve always had a major fascination for invertebrates. Mainly butterflies and moths, but other species aswell.  Raising and breeding them was the next logical step! And over time I have acquired a lot of footage and information of the life cycle of many species. I decided to do something useful with it and create a website to distribute this information.

Most of my knowledge is from self-study and observations from rearing captive insects. Much of it is trial and error  and studying the life cycle of species I want to breed, and trying to recreate the natural conditions they require. I haven’t done any “official” education on insects although I read as much as possible about them and have learned a lot from talking to professionals and entomologists. I am also an amateur level researcher and write and publish my own entomological publications. If you scroll down, you can find my contact information. I am always eager to answer questions and talk to other people who are passionate about butterflies and moths!

For questions:
Email: bart.coppens@hotmail.com (meight take a few days, I don’t read my mail that often, but I’m open to it!)
Facebook: Click here (Send me an inbox message – disclaimer, I get tons of messages every day and some slip past my attention or Facebook puts them in the spam box. Once again my apologies, but there is a small chance I won’t see it. I try my best to answer them all!)
And my username on Actias is “Bartmantis”.

Hopefully this website has gained your interest! Invertebrates need more respect as pets, many people underestimate their importance, beauty and diversity.

Thanks for reading, I hope you enjoy reading my website! – Bart Coppens


And now for some selfies througout the years..
