While on the ground, there is busy traffic on leaf-cutter ant highways. In one direction, ants bring back pieces of leaf to their colony. In the opposite direction are the ants which yet have to get a piece of leaf.

New jellyfish discovery in Dutch Wadden Sea


This video is called Diving with JAGO: jellyfish / Medusae perform their gorgeous dances.

The Dutch Wadden Sea Society reports that a jellyfish species, new for the Netherlands, has been discovered.

Mitrocomella polydiademata was found near the Balgzand.

This rare species does not have a Dutch name, or an English name, yet.

Very little is still known about the way of life of this species, and its relatives, the Medusae jellyfish. So, research will continue.

Costa Rican flowers, butterflies and bees


Orchid bee

This is a photo of an Euglossa orchid bee. Photographed in Alajuela, Costa Rica, on 14 March 2014.

Orchid bees are important pollinators in Costa Rica.

The orchid bee of the photo was probably attracted by the beautiful flowers nearby.

Zebra longwing

Apart from the postman butterfly which I already mentioned in another blog post, these flowers also attracted other butterflies, like this zebra longwing.

Butterfly, Costa Rica, 14 March 2014

There was also the butterfly on this photo. I am not sure about its species, as there are various orange-coloured butterflies in Costa Rica.

Stay tuned for more on the Poas volcano, and other Costa Rica stuff!

Dutch butterfly spring news


This video is called Astonishing European Butterflies and Moths.

The Dutch Butterfly Foundation reports that never before so many butterflies have been seen so early in March as during the mild spring weather of last weekend.

About 99% were butterflies which had wintered as adults, like small tortoiseshell and brimstone.

However, there were also already some which had wintered as pupae: large white, small white, green-veined white, holly blue and speckled wood.

Various large tortoiseshell individuals were seen as well. This butterfly species was considered to be extinct in the Netherlands. One should hope it is coming back.
