Discover Nature’s Wonders: Green Balls, Salamanders, and Coral Fungi in Bergen op Zoom

Sure! Let’s dive into this delightful nature-themed article, shall we? If nature is out there flipping through channels, clearly, it’s caught the Forest Ranger Frans Kapteijns show on repeat! It feels like a botanical Q&A session, and honestly, I can almost hear the nature; it’s like being serenaded by the silence of the forests while waiting for those magnificent green balls to spill their secrets.

What’s Up with the Green Balls?

So, the first bit of mystery involves Sander Castelijns finding peculiar green dots on a semi-paved ground. "Are they alien eggs?", you might ask. Nope! Turns out they’re none other than blue-green algae, specifically a splendid strain called Nostoc pruniforme that doesn’t even have a Dutch name yet. I mean, that’s bold! When your algae doesn’t even want to take on the existential crisis that is a name!

And now here’s the kicker: it’s not even real algae; it’s basically high-functioning bacteria. The Dutch might call them “green balls,” but in England, they’ve affectionately dubbed them “Mare’s eggs.” Oh, I can just picture a farmer wandering around his fields with a basket, “Why yes, I do collect Mare’s eggs! And no, you can’t fry them!”

The Salamander Saga

Then we have our lovely correspondent Yvette van Baarle stepping into the role of amateur herpetologist, encountering what she believes is a pin-legged salamander. But hold your laughter – the true nature of a salamander is multilayered. The fin-footed salamander has black webbed feet during mating (sounds fancy, doesn’t it?) but this little feller was dry and land-bound. What’s fascinating is that this tiny creature, measuring only 9 centimeters, got to strut its stuff amongst newts that are larger yet less interesting! It’s a real David versus Goliath scenario—except one just wants to be adored.

And can we just applaud Yvette for stepping outside and engaging with nature? I wouldn’t even know how to name a plant, let alone spot a salamander.

Bugged Out in Crete

Now, Kees Konings hits the jackpot—thinking he found a beetle in Crete! Surprise! It was a knapweed shield bug playing dress-up. You know, like a beetle who just finished a seminar on “The Art of Mixing with Meadows 101.” And let’s give a round of applause for this little bug’s culinary preferences: wild carrots and daisies. Honestly, if I had to choose a salad too, that would be it—viva la bug salad!

Coral Fungi or Underwater Garden?

Moving to the exotic side of fungi, we meet Marianne Wijten, who stumbles upon what she initially interpreted as coral in a forest. Imagine the shock! “Wait, am I in an aquarium?” Nope! It’s the stunning straight coral fungus. An Instagram post waiting to happen. It looks beautiful on wood chips but doesn’t get you a wave from the ocean. Not all underwater wonders are.

A Spanish Flag in the Garden?

On to Winny Stegwee, who blessedly had a lovely Spanish flag moth drop by. Let’s just take a moment to appreciate this bright little creature waltzing in like it owns the garden! You thought your ‘garden party’ was fancy? This moth just added a flair of Mediterranean glamour!

Nature Awaits!

For those feeling inspired and ready to ditch the couch, Frans Kapteijns has thrown down the gauntlet—with urban nature excursions happening right here in Oss! Put on those sturdy walking shoes and prepare for a nature morphing into a coffee and tea affair. Lovely! Unless the nature itself decides to join in with little bugs and balls trying to photobomb every group picture.


So, whether you’re a nature nerd or just someone who gets way too much joy from spotting green spheres, there’s something for you in this delightful post. And remember, whatever you encounter, from blue-green algae to fabulous night-flying moths, there’s always a quirky story behind it! It’s a wild world out there, folks – get out, explore, and don’t forget to flaunt your findings!

And who knows? Maybe you’ll even end up on a podcast!


We’ll sum this up with a cheeky reminder: nature might be quietly waiting outside your door, but it’s definitely not shy about the shenanigans it brings!

Waiting for privacy settings…

What are the numerous green spheres found on the semi-paved ground?
Sander Castelijns noticed an array of vibrant green balls scattered across a damp area of semi-paved ground at his workplace, piquing his curiosity about their nature. The green spheres are identified as blue-green algae balls, specifically a unique species known as Nostoc pruniforme, which currently lacks a Dutch designation. Interestingly, referring to them as ‘blue-green algae’ is a misnomer, as they are actually a form of bacteria. These peculiar formations commonly appear in various regions following heavy rainfall, often clustering near puddles. The species is harmless and can be found globally. In England, these delightful green spheres are affectionately termed Mare’s eggs. For further insights, you can read more here.

Identified in the Blaak district of Tilburg: Is this a pin-legged salamander?
During a jaunt in the Blaak district of Tilburg, Yvette van Baarle stumbled upon a salamander and pondered if it was a pin-legged salamander. These fin-footed salamanders display distinct black webbing between the toes of their hind legs, especially during mating season, as illustrated in the accompanying photograph. Although small newts lack this feature, the confusion arises as we increasingly encounter gilled salamanders above water. As Yvette caught a photograph of the creature out of water, determining its classification becomes challenging. Based on her description, I concur that it is likely a pin-legged salamander. Fin-footed salamanders appear lighter in land form compared to small newts, which tend to exhibit darker, browner colors. Additionally, while small newts can grow to 11 centimeters, the pin-legged salamander reaches a maximum length of 9 centimeters, indicating that the fin-footed salamander maintains similarities to the smaller newt.

What insect did Kees Konings find in Crete?
Kees Konings believed he had spotted a beetle during his time in Crete, but a closer inspection revealed it to be a bug instead. Upon analysis, it appears to be a knapweed shield bug, typically seen in meadows and along the edges of fields, primarily between the months of April and September. This species is widespread across Europe, extending all the way to Sweden. The knapweed shield bug primarily feeds on umbelliferous plants like wild carrots and daisies. Following their mating rituals, females lay eggs on the foliage of various herbaceous plants. Upon hatching, knapweed shield bugs undergo incomplete metamorphosis, progressing through five nymphal stages before reaching adulthood.

What fascinating find did Marianne observe in the Bergse forest?
In the serene surroundings of the Mattemburgh forest near Bergen op Zoom, Marianne Wijten encountered a stunning sight unlike anything she’d seen before. She discovered the straight coral fungus, known for its visually striking, multiple branching appearance that resembles underwater coral. This particular fungus is part of the stem fungi family and typically thrives on wood chips, branches, plant debris, and tree stumps. Its growth pattern varies depending on the type of wood it inhabits; the fungus becomes considerably more branched when growing on coniferous wood compared to deciduous trees, which provides a distinct visual aesthetic characterized by orange-tinged branches.

Beautiful photos section
Winny Stegwee shared a delightful experience, stating, “This stunning Spanish flag moth visited my garden in Rijen,” showcasing the enchanting beauty of nature.
