It’s a remarkable discovery that has sent ripples through the world of malacology (the study of molluscs). No fewer than seven snail species never before found in Belgium have been unearthed in Wallonia. Seven may not seem many. However, the country’s existing snail count is only around 110 species. So this is a significant addition to Belgium’s biodiversity.
This week’s edition of the Belgian Journal of Zoology reveals that these new species were discovered in the most unexpected of places – building material dumps.

Four of these species are not entirely new to the European continent, but the remaining three can be traced back to China or Vietnam. (These Asian snails were all found dead, which is probably for the best, given their reputation as severe agricultural pests in their countries of origin.)

The researchers believe that the snails made it to Belgium by hitching a ride on building products such as bricks, tiles, stones and other quarry products. They likely survived for months tucked away within their shells.
The credit for this exciting find goes to researchers Louis Bronne and Johann Delcourt from Natagora and the University of Liège. Their relentless exploration of stone yards in Wallonia in 2022 and 2023 finally led them to these hidden treasures.
Does their discovery inspire you to search your local building materials dump?
I created Discovering Belgium in 2011 to share the country’s hidden stories, fascinating places, and remarkable people. Through articles, photography, and audio walks, I share discoveries that reveal Belgium beyond the obvious. Hope you enjoy this site.
Fine, you keep them there Denzil my garden has enough to cope with! ?
Too late, I have just posted a few over to your address.
🙂
Spare me, please! 😀 😀 😀
Don’t count on me finding more species of snails. I respect them for their place in our natural ecosystems but I’m no fan.
And I thought a snail was just a snail. I can’t say I’ve looked closely to see if there’s a difference. We don’t have many in our garden because our resident blue-tongued lizard enjoys snails for lunch.
I don’t object to snails, but I’m sure we have enough already 🙂
