Description: Sicus ferrugineus. There is no english translation for this species, maybe you can say thick-headed fly. It places its eggs onto the bumblebee's torso, then the bumblebee carries the egg to its hive and the fly larvae feed upon the inventory.

In the middle of the night we had a lightning storm, so I decided the smart thing to do was to go take pictures of it. Little did I know the lightning was less than a mile away; the strike you see here was certainly hitting the water. The sound of thunder followed almost immediately.

Acer grandidentatum Bigtooth (a.k.a. Wasatch or Rocky Mountain Sugar) Maple leaf detail in autumn. Little Cottonwood Canyon, Salt Lake County, Utah.
Pollen from a variety of common plants: sunflower (Helianthus annuus, small spiky sphericals, colorized pink), morning glory (Ipomoea purpurea, big sphericals with hexagonal cavities, colorized mint green), hollyhock (Sildalcea malviflora, big spiky sphericals, colorized yellow), lily (Lilium auratum, bean shaped, colorized dark green), primrose (Oenothera fruticosa, tripod shaped, colorized red) and castor bean (Ricinus communis, small smooth sphericals, colorized light green). The image is magnified some x500, so the bean shaped grain in the bottom left corner is about 50 μm long.

LARGER On Black Ocellaris clownfish, Amphiprion ocellaris. Some clown anemonefishes are brave. When divers close to them, papa anemonefish will swim out to defense. (Looks like very angery!!)
But, oftenly they will hide.(papa will hide faster than their babies. haha~)
Lovely!!Before the year 2004, only two tropical cyclones had ever been noted in the South Atlantic Basin, and no hurricane. However, a circulation center well off the coast of southern Brazil developed tropical cyclone characteristics and continued to intensify as it moved westward. The system developed an eye and apparently reached hurricane strength on Friday, March 26, before eventually making landfall late on Saturday, March 27, 2004.
The crew of the International Space Station was notified of the cyclone and acquired excellent photographs of the storm just as it made landfall on the southern Brazilian state of Santa Catarina (the storm has been unofficially dubbed “Cyclone Catarina”). Note the clockwise circulation of Southern Hemisphere cyclones, the well-defined banding features, and the eyewall of at least a Category 1 system. The coastline is visible under the clouds in the upper left corner of the image.

Canard "broutant" une accumulation de plancton a priori constituée de cyanophycées (autrefois classées comme "algue bleue"). Dans ce cas, quelques heures (ici une quinzaine d'heure) après le début de l'épisode d'inflorescence, les taches bleues se sont étendues et elles s'accumulent sur les bords d'une pièce d'eau (bras d'ancien canal, aujourd'hui fermé).
Les traces en forme de trainées sont des traces laissées par des poissons et des canards qui circulent sur l'eau, "cassant" le biofilm.
La couleur bleue caractérise des zones d'accumulation de pigments bleus libérés par des bacéries mortes. Ici l'eau a une consistance de «soupe» sur les 5 à 10 mm, sous la surface.
Lieu : quai du Vault à Lille, non loin du centre ville (France), après une longue période pluvieuse (non caniculaire, et même sous les moyennes saisonnières, mais avec des nuits inhabituellement douces). Le canal proche (Deûle) est également couvert d’une couche de plancton vert sur de vastes surfaces (centaines de mètres carrés), mais beaucoup moins épaisse. Les échantillons dégagent une forte odeur d'algue (type spiruline).
