There are many “firsts” this time of the year! Here are the first flies of the year as well –
The first picture shows a Flesh fly (Sarcophagidae) sunbathing on a staircase. Flesh flies look a lot like house flies, but are generally larger. They are gray, have a checkerboard pattern on the top of their abdomen, three black stripes running along the top surface of their thorax just behind the head, while house flies have four, and sometimes a reddish-brown tip at the end of the abdomen.
The second picture shows a Yellow dung fly (Scathophaga stercoraria), or – if you want to make the name sound a bit nicer, which could be a challenge for a dung fly – also known as Golden dung fly. I think it’s a female as she has a more of a green tone to her rather than yellow. These flies are very important in the scientific world due to their short life cycles and susceptibility to experimental manipulations, thus have contributed significant knowledge about animal behavior.
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-
Flies are annoying little creatures whose only point in life is to serve as food for other animals, right? No, that’s not entirely true. Without flies, we would be knee deep in rotting food, feces, decaying vegetation, animal corpses, etc. So even though flies can be incredibly irritating: consider a world without them..
Here are a couple of snipe flies, more specifically identified as Chrysopilus splendidus. Such a nice name, sounds a bit like a spell from the Harry Potter books, doesn’t it! 🙂
Chrysopilus is a worldwide genus of predatory snipe flies, there are about 300 species in the genus, including fossils found in amber.
Week 23 = June = It’s summer! And today’s a bank holiday, which is the best kind of Monday one can ask for 🙂
Here are some pictures of small lives taken this morning: (Pictures were taken. Not lives.)

PS. Anyone else having issues with WordPress email notifications?
A Calliphoridae fly also known as “Blow fly”, from an older English term for meat that had eggs laid on it, which was said to be fly blown. He was blowing a bubble of water, and then inhaled it again. There are many theories for this behaviour (to aid digestion, to cool the body, being sick, cleaning their mouthparts etc.) but no one knows for sure.

When I was a child, I thought these flies were unusually fast little bees or wasps but their coloring is a Batesian mimicry and they’re harmless. In fact, they do a lot of good as their larvae prey upon pest insects (which spread some diseases such as “curly top”) and adults feed on nectar and help to pollinate the flowers (which probably is why they’re sometimes called flower flies).
The yellow dung fly (Scathophaga stercoraria) spend their lives on dung, or looking for it. They are predators and the dung supplies their breeding and hunting ground. They hunt by ambushing insects visiting the dung. Here’s a male dung fly having dinner, its prey so big that I first thought I was interrupting an intimate moment with a lady dung fly 😉
This fly has a second face in its face! 😀 It kind of looks like a cartoon character wearing huge headphones.
Anthrax anthrax, is a species of fly in the family Bombyliidae. It’s a fairly large fly, the body length is 10 mm. The body is black with four white markings at tergum 2 and 3 and two white markings at the end of the abdomen. Tergum 1 is black with tufts of white hairs at the side (visible when hovering, thus not in this picture). The wings are mostly black, only the tops are transparant, and the veins are dark brown. It kind of looks like the wings have been painted with watercolour, I think the pattern is quite nice. 🙂
