This time in Stuifmail a glassy-winged moth, creatures falling from a Christmas tree, a jelly-like mushroom and slippery earthworms. Skovrider Frans Kapteijns answers questions.
Omroep Brabant also broadcasts the television program ‘Op pad’ on Tuesday, where viewers are taken into the nature reserves of Brabant’s Landschap. As a viewer, you can also follow the route from the program yourself. A walking app has been developed especially for the program.
Behind the kitchen window was a beautiful insect with beautiful transparent wings
Evelien Reijns ten Berge sent me a photo of a dark, almost black butterfly. What also immediately stands out are the transparent wings. We are therefore dealing with a butterfly of the moth family of wasps or glass butterflies, and I think it is the berry glass butterfly. It is a very special discovery, because although the berry glass butterflies are quite common in our country, they are rarely seen. I myself have only come across this species of moth once. You will most often encounter these moths in bushes with berries, hence the name. Examples of bushes are currants, blackcurrants and gooseberries. These types of bushes are the plants that the caterpillars feed on, so you see them primarily in allotments and gardens where a lot of berries grow.

The Christmas tree had only been inside for three days and suddenly insects fell out. What are they?
Rita Folker sent me a picture of an animal, some of which fell out of her Christmas tree, and she wondered what animal she was photographing. On the ground you can actually see a very small animal, and I think it is an adult aphid. In the picture I can’t really see which species it is, because there are several species of aphids. In addition to black aphids, you also have green, purple, red, yellow and white aphids. In principle, all aphids are herbivorous insects that feed on plant sap with stinging and sucking mouthparts. They are also usually seen at growth sites for trees, shrubs or herbs. This is because at the growth sites, such as flower buds or leaves at the top of a stem, the sap flow has many nutrients. And the latter makes sense, because plants need that to grow.
Under the oak tree was a jelly yellow thing, what is it?
Jan Pouels found a yellowish substance under an oak tree and said it felt like jelly. We are therefore dealing here with the yellow jelly mushroom. These mushrooms are easy to recognize by their gelatinous, lobed fruiting bodies that are golden yellow in color. In the beginning, the fruiting body is orange-yellow in colour. At full maturity this changes to golden yellow. As they age, the color fades to sulfur yellow to become almost white as they decompose. Yellow jelly mushrooms grow almost all year round, especially when it starts to get cold in late autumn. Yellow jelly mushrooms thrive on dead branches and on the trunks of various deciduous trees such as beech, oak, ash, hornbeam and hazel. They are quite common. In the Netherlands they are known as inedible mushrooms, but they are eaten in the Far East. Be careful with this, because the yellow jelly mushrooms that grow there may be different from the ones here in the Netherlands. Maybe just because they grow there on a different type of substrate than here.
Every winter there are all upright sticks between the paving stones
Jeanne Meijer finds upright sticks between the paving stones every winter, and she wondered what was going on. Earthworms live under her paving stones, and at night these animals become active and look for food. All types of plant material are so suitable and they pull them down through small openings. But the moment a piece is available to eat, they already start, meaning that if it is a longer twig, it will still stick out above the ground. If you leave it, you will see that it is gone the next day, or that only a small part of it is sticking out over the stones.
Pheasant in the backyard, is it unnatural?
Diana Liebregts saw a pheasant darting around their backyard on New Year’s morning, and she wondered if it wasn’t a little unnatural. I can’t say unnatural, because pheasants go wherever food can be found. If Diana thinks the pheasant is unnatural in the Netherlands, then I say yes. Our famous pheasants do not occur naturally in Western Europe. Well in Georgia, Armenia, Azerbaijan and from Vietnam to North Korea. Thanks to the Romans, who valued the pheasant for its meat, these animals spread throughout Europe. However, the major growth in the European pheasant population took place later, namely for pleasure hunting. In the Netherlands it is also forbidden to breed and release pheasants. Unfortunately, it is still done illegally by hunters.

That’s why worms are indispensable to our soil – ZEMBLA_BNNVARA
Release: December 7, 2020
Researcher Jeroen Onrust (31), also known as the worm man, has been researching earthworms for ten years. He takes us to the farmland where he shows how important the red worm is to the fertility of the soil. But Onrust makes a disturbing discovery in his research: There are fewer and fewer worms. “Plowing has a disastrous effect on the worm population.”
Black robins appear daily on the third floor in Breda
Harry Verheyen gets to see the black redstart on his balcony every day. Probably because he also puts the right food in a big basket, because black redstarts are generally shy birds. Originally, the black redtails lived in rocky areas with many canyons. Now buildings and houses are the rocks for them. Canopies, holes in walls and other open spaces are now their places to breed. In addition, the urban area is also warmer than the countryside, and they feel completely at home there. Harry lives in such an urban area in Breda and also three high, ideal for the black redstarts. The menu for the black red start contains the following ingredients; crane flies but also various other insects. Insect larvae and larvae are also on the menu in addition to all kinds of spiders. The advantage for the black redstarts in the cities is that there is a lot of artificial light and they also hunt insects at night. After autumn, seeds, berries and other fruits also appear on their menu.
Birds sometimes hibernate in nest boxes, isn’t it better to leave the old nesting material in it?
Antje de Bruyn wondered if the nest boxes, where the birds hide in severe cold, should be cleaned? Is the old nesting material really beneficial for them because it gives them a little extra warmth? It is true that the nesting material provides extra warmth, but if it is colder and the birds really have to seek shelter in those nest boxes, then it is not the nesting material that causes concern, but what is in the old nesting material. . There are also fleas, mites and various bacteria, and if the birds have become weaker due to the cold, they are the ideal prey for these kinds of pests. It is therefore best to clean the nest boxes completely after the breeding season, at the beginning of autumn. If it gets so cold that they take shelter in it, they provide enough warmth by sitting close together.
