Week 41! Today I photographed some mushrooms (no idea what kind!), and a small fruit fly (Drosophila melanogaster?) who was sitting on one of the “rooftops” 🙂
Week 40 – Autumn is here but we still have some flowers 🙂
I visited Hortus Botanicus the other day, it’s a botanic garden in Amsterdam and one of the oldest in the world (founded 1638). There are more than 4,000 plant species to see, but I spent most of my time there in a small butterfly greenhouse 🙂
(1) The Julia butterfly (Dryas iulia) originates from South and Central America but because of the bright orange color it’s often called “The flying Dutchman” as orange is the national color of the Netherlands.
(2) The Zebra longwing (Heliconius charithonia) can make a creaking sound by wiggling its body. They do this when disturbed but even though I would’ve liked to hear it, I didn’t want to alarm him so I still don’t know what it sounds like.
This little Oak bush-cricket (Meconema thalassinum) has been sitting on my bicycle for over a week, clinging to the basket as I’ve been biking around town almost every day 🙂 It’s a small cricket, about 1.5 cm long with very long antennae, usually not found on bicycles but in he foliage of trees (including oaks, where the female lays eggs under the bark).
In America, it’s known as the Drumming katydid, probably because the male drums on leaves with his back legs. (Click here to listen!)
Never really noticed it before… Bumblebees have very long tongues! But a study (Science 349, 1541–1544) has shown that bee tongues also tell a tale of climate change; warmer temperatures lead to fewer flowers which in turn yield shorter bee tongues. et al.
When we think about iconic climate change images, we usually picture a polar bear clinging to a melting piece of ice. We (most of us, anyway) don’t think about a bumblebee, flitting about an alpine meadow with a shorter-than-average tongue. Still, it’s a very interesting study, I recommend reading it.
One of the best things about photographing bugs is that you can be lazy and lie down in the middle of a meadow and just point your camera to all the little critters around you! 🙂 Here are some shots of the guys that kept me company in the meadow-
(1) Small copper butterfly (Lycaena phlaeas), which in Dutch is called “Little fire butterfly”. The name phlaeas is said to be derived either from the Greek phlego, “to burn up” or from the Latin floreo, “to flourish”. (I shot this picture through the grass and didn’t get a chance to take another one.)
(2) Lesser marsh grasshopper (Chorthippus albomarginatus), with a sound like the winding of a mechanical clock.
(3) Speckled wood butterfly (Pararge aegeria), always cooperative and sit still long enough to have their portrait taken.
(4) Scorpion fly (Panorpa communis), this is a male as evidenced by the scorpion-like tail (females don’t have it). It’s in fact its genitalia, and it doesn’t sting! See close-up below.
A female Common blue butterfly (Polyommatus icarus), photographed in Amsterdamse Bos today. Living up to its name, this is perhaps the most widespread and common blue in Europe. Their lifespan as a butterfly is only 3 weeks, so it’s important to make the most of each day and really enjoy life to the full.. Like spending the day in a flower field in the sun! They’re so pretty and I’m always happy when I see one of these little guys 🙂
And apparently it’s been five years since I started blogging! Yay me 😉
Week 28 already! What happened to time, more than half of the year has passed already and now the days are now getting shorter and darker again.. Not that we notice it, in the midst of Summer! 🙂
Here’s a mix of pictures of bugs enjoying the good weather we have here in Amsterdam-
Today I’ve been photographing snails. Not my favorite animals, but quite interesting in their weirdness 🙂
The Roman snail (Helix pomatia), a.k.a. Burgundy snail or escargot, is a species of large, edible, air-breathing land snail, a mollusk in the family Helicidae. These were introduced by catholic monks in the middle ages. The monks came to spread knowledge and religious traditions, including fasting where you’re not supposed to eat anything. Except snails, apparently! They were allowed, so the monks brought snails with them. Still today, escargots are eaten in many countries and in France alone they eat more than 500 million per year!
Look at that face.. It has four tenacles, and you can see the eye spots at the tips:
They’re very big, around 10 cm long and the shell is about 5 cm tall. In the picture below it looks like the Roman snail “attacked” or ate the Grove snail, but it didn’t. They are vegetarians, and not cannibalistic. But notice the difference in size compared to the Grove snail:
Here are two Garden snails (Cornu aspersum). I think they might have been mating, but I’m not sure. Maybe they were fighting (do snails fight?) or just hanging out together. This is another kind of edible snail, in France it’s called “Petit gris” and in Spain (mainly in the Andalusian region) you can hear street vendors shout “Caracoles! Caracoles!” when they sell these as snacks.
Here’s a little Grove snail (Cepaea nemoralis), dining on a dead leaf:
And finally, here’s a picture of a local hotspot:
This Buff-tailed bumblebee (Bombus terrestris) is having a productive day, you can see that her “pollen basket” (the real name is corbicula) is almost full 🙂
The basket is the bumblebee’s storage, it’s made out of hard hairs on the flat part on its back legs. When she walks around in the flower, pollen is collected all over her body and then she sort of “combs” it into the basket. Only nesting female bumblebees collect pollen, the males don’t have any baskets.
Zoom in on the basket:
