While family members continue their hard work, one ant is struggling to survive. It is trapped in the resin flowing in the three. Click here for the larger version.

The nest NLLI-581 was discovered in the winter of 2009. The position of the nest is different from the many other nests in the database. This nest is located two meters from the edge of the stream and swamp. We asked our self the question if this mound could be a nest. Because it was winter we could not confirm. Some weeks ago we revisited the nest and thousands of ants were taking a sunbath. So we confirm there can live ants near the water. But 25 meters away we discovered a second nest, connected by a ant road. This nest is even closer to the water!

There are several funny details about these two nests:

• Both nests are very close to the river bed, which is not very common for wood ants. Especially when you know that a better habitat (dry, high, spruces and beeches) just 10 meters away. Why do they choose the wet location for the nests?
• There are two nests and it appears that there is the same species on both nests. Polydome or monodome?
• In nest NLLI-582 the ants are carrying materials high up in the dead oak. Are they building a nest 5 meters in the sky?
• One photo, nr 3 shows 4 ants carrying parts of ants from NLLI-581 to NLLI-582. But both nests are the same species. What happens?

So, some research is needed.  To be continued.



Back to start point

• A Thach: This layer of material can be adjusted to weather conditions
• B This layer isolates the nest and makes the mound solid.
• C Coarse material is dry and contains the pupae chambers.
• D Almost all nests are built on and around a rotten stump.
• E In the soil beneath the nest are also many rooms and spaces
• F The sand excavated is left outside the nest

• 1 In the pupae chambers the ants take care of the pupae.
• 2 In these protected rooms the eggs are kept
• 3 Also the ant larvae are kept in these well protected spaces

• I The queens room is in the center of the nest, mainly beneath the tree stump.
• II The grave chambers are far away from the main nest sructure.

Acacia ants

• Pseudomyrmex ferruginea
• Pseudomyrmex flavicornis

Photo’s below: probably Pseudomyrmex flavicornis

This map shows my first wood ant super colony. This is one of the five large wood-ant supercolonies with this size of road structure. In 2010 all five will be revisited and re-mapped.

Here you will find basic information about wood ant protection and about the protection-project Floriade Venlo
