Do you ever see a half -eaten bumblebee in your garden? Then he probably fell victim to a murderous fly. Forester Frans Kapteijns tells more about it. He shares his knowledge of nature every week and everyone can submit questions via [email protected]. Share one of these driftmail was published on Saturday morning.

Seen on a terrace in Borkel and Schaft, is this a flying deer?
John de Koning saw in Borkel and sells an insect that looked like a flying deer. That was true: it was a small flying deer. This insect becomes a maximum of three centimeters in size, while the ‘real’ flying deer can become nine centimeters. In addition, the antlers-like jaws of the real flying deer are huge, while those of the small flying deer are very small. You can find them in deciduous forests, where they live from leaves and tree juices. There are leaves and juice of trees on the menu of these insects.

Dead bumblebees in the garden?
Two readers were worried about dead bumblebees in their garden. Bets friend and her daughter saw dead bumblebees without a head in the garden and they wondered if parasites could kill bumblebees. That’s right. The bumble bees at their in the garden are victims of the bladder fly. The female lays eggs in a bumblebee, after which the larva eats the animal from the inside. The affected bumblebee just goes back to work while she is slowly eating empty from the inside.

José Buitendijk found dozens of bumblebees with holes in their heads. This can be due to a shortage of nectar. But there are also several animals, those weak bumble bees to eat. Even birds like bumblebees. But ants and other insects can also catch bumblebees and tear their heads to eat both the contents of the head and the rear body. In addition, bumble bees can suffer from diseases or die of injuries. Both can then give rise to death and the death of the head.

What is the name of this songbird?
Mari Kapteijns thought he would see a robin tap on the Kampina. Those birds can really see a lot and it is a typical habitat of the robin tapuit. Yet he did not see a robin tap, but a special bird for that area, a collared redstart. That is a migratory bird that leaves for Africa in winter. They mainly live in old forests on sandy soil. The males are strikingly colored: orange chest, black face and a leig -free back. Their menu consists of insects, larvae and berries.

A pink with yellow butterfly
Liz van Zimmeren saw and photographed a small butterfly, landed on a garden chair and she wondered which butterfly she had seen. The name of this butterfly is the rose petal and this is a day -active moth. After mating, the females lay eggs in small clusters on tree bark. Caterpillars come out of the eggs, who live on the branches of deciduous trees. In the trees they mainly eat lichen, including large leather moss. Most you can come across those caterpillars on beech, summer oaks and birches. The caterpillars under the bark do the hibernation and later they pupate in a sturdy spider with, among other things, their own hair.

Natural tip: desert walk through the Brabant Sahara
Sunday, August 31, from ten in the morning to half past one in the afternoon you can participate in a walk through the Loonse and Drunense Duinen.

The Loonse and Drunense Duinen are also called the ‘Brabant Sahara’. With sunshine and clear air, the temperature in the summer can rise to up to 50 degrees. But how does that feel on a warm summer day? We start at the memorial monument in honor of 14 resistance fighters. We walk further over the wheelchair path to the vantage point, where you can enjoy a beautiful view and you experience the vastness of the Loon and Drunense Duinen.

If you are not yet convinced, that will do the more than 500 year old oak, which we are going to look up and has a circumference of 5.50 m. What does the Sint Jansberg have to do with Efteling? And is there also evidence that the dunes were a military training grounds years ago? Participate in this special walk, where we will of course also talk about plants, animals, drifting sand recovery, management and maintenance.
