The Joy of Spring

I realise that at first sight it might seem strange a message about bees and butterflies. Because the effective period in which plant can be studied is limited to about two months I've started to study Bees and Wasps. And insects as you all might know are very related to plants (pollination). So in early spring I'm always on the hunt for Hoverlies that have hibernated, Andrena Bees and Bumblebees. Yesterday I finally had succes!

Last few days I already visited the botanical garden next to my school. Due to the presence of clouds and a low air temperature I wasn't able to spot any Bees or Hoverflies. Last saturday I saw my first Bumblebee of this year. It was a Buff-tailed Bumblebee (Bombus terrestis).

Yesterday I had better luck as I already mentioned. I've started a bit uneasy with my insectnet. Most of the times I tell people to stay an arm and net length away from me. This because I might swing my net round. So fast as I was last year so slowly I started yesterday.

Below you'll find a list of the species I've spotted yesterday. Also I've included photo's of some.

• Buff-tailed Bumblebee (Bombus terrestis)
• Red-tailed Bumblebee (Bombus lapidarius)
• Common Carder Bee (Bombus pascuorum)
• Early Bumblebee (Bombus pratorum)
• Hairy Footed Flower Bee (Anthophora plumipes)
• Unkown male Miningbee (Andrena spec.)
• Unkown dwarf male Miningbee (Andrena spec.)
• Waspbee species (Nomada spec.)
• Marmalade Fly (Episyrphus balteatus)
• Drone Fly (Eristalis tenax)
• Comma (Polygonia c-album)

The search for rosettes continues in Belgium

Last wednesday the search continues. This time I started my walk at the trainstation in Maastricht. From there the trip took my over the Sint Pieterbergs to Thier de Castert and through the locks of Lanaye to a small grassland. I've posted some scenic pictures of the trip below.

In the past Monkeys Orchis (Orchis simia), Man's Orchis (Orchis anthropophorum) and Bee Orchid (Ophrys apifera) were reported here. I had good hope that I would find rosettes of the afore mentioned species. After I've entered the small grasslands I soon found the first rosettes. It appeared that they belong to the Bee Orchid (Ophrys apifera). In total I've located between forty and fifty rosette of this species. Later on I've spotted some rosettes that belong to the Lady Orchid (Orchis purpurea), at least that's what make of it. Unfortunatly I wasn't able to locate any rosette that belonged to the Monkey Orchis (Orchis simia) or Man's Orchid (Orchis anthropophorum).

Leaving Belgium through the locks I continued my way to Maastricht through the Jeker valley of which I've posted a picture below.

Search for rosettes continues

Last weekend I came to see the rosettes of the Bee Orchid (Ophrys apifera) in Leeuwarden. By far this is the most northern station of the species. Although in 2008 someone reported a specimen on the isle of Texel.

It was in 2006 when Hinko Talsma first discovered flowering plants in a road verge. The following year's the plants flowered. Mr. Talsma also contacted the muncipality of Leeuwarden because their present management was inadequate. Although the muncipality was brought up to date of the findings the contracter -who actually executes the measures- decided to mow when plants were flowering.

Hinko was so kindly to show me the road verge were we soon located five rosettes. The individuals were spread out over two road verges. Below is a picture included of one of the rosettes.

Search for rosettes

Last thursday me and my girl-friend went on a field-trip through the countryside of southern limburg. Our main goal was to locate rosettes of early flowering orchid species, and to enjoy the staggering scenery for which this area is know for.

The trip started in Valkenburg a/d Geul. After a substantial climb we've left the Biebosch and the St. Jansbosch behind, and the Gerendal welcomed us. The frolicking walks of several lambs made clear that spring already started, and after a short lunch we continued our walk. Seeing the vegetation as it was I had little confidence we were to find any rosettes. But four eyes see a lot more than two, and it was my girlfriend who spotted the first rosette of Lady Orchid (Orchis purpurea).

Shortly after our first find soon showers appeared, and as we learned they never went away that day! Sporadicly there were some clearings. The hamlet of Beertsenhoven brought us to Gulpen. Soon we continued our way to the last site were we found rosettes of two more orchid species. The first one is the rosette of a beautifull mediterranean species that occurs only in the coastal region and uplands of southern holland. In the southern part the Pyramidal Orchid (Anacamptis pyramidalis) is a true rarity and is only known of a hand full of stations. In total we've found about 40 rosettes! That's the same number of flowering plants I've found last year. So I cautiously conclude that the severe winter (frost periode) has had no impact on the individuals within this population.

A nearby grassland contained several rosettes of the Bee Orchid (Ophrys apifera) last year. But the owner decided to mow the vegetation when the plants started to flower. Small Broomrape (Orobanche minor) also appears here. This year we've found an decreasing number of rosettes at the known station. Let's hope these plants are spared this year and they will welcome us with the beautifull bee-like flowers.
