🕷️ A #spider for #MacroMonday. This is a six-spotted fishing spider, Dolomedes triton, in my goldfish pond. #macro #photography #spiders
A spider is on the surface of water. It has 3 legs on a leaf, with the other legs on the water, causing slight indentations on the surface, skewing green reflections. The spider has thick legs, a white band around its body, black and orange stripes on its abdomen, with white spots on the black stripes.

Adult Nursery Web spiders, in their various patterns and colours, can be seen throughout the UK at present. They live in a variety of habitats but perhaps the best place to find them is amongst banks of bramble, nettles and other tall plants. Later, watch out for females carrying their egg sacs.

A likely Leiobunum sp. harvestman. Striking colors against the background here. I wish more people looked past the blur of those long legs to see the beautiful animal behind them. #bugsky 🪲🪳🌿
A vivid close-up photograph of a harvestman, likely in the genus Leiobunum, perched on a lush green fern. The harvestman has a strikingly orange body with a textured, almost pebbled carapace and glossy black eyes positioned at the front of its small head. Its body is compact and oval-shaped, with several small, articulated legs near its front that seem to aid in sensing or feeding. The most visually dominant feature is its long, dark brown to nearly black legs, which radiate outward in all directions and stretch well beyond the edges of the frame, creating dynamic lines across the background. The fern beneath the animal is a rich green, with detailed, feather-like fronds. The contrast between the orange body and the cool green leaf provides a visually stunning color palette. A few tiny grains of soil or sand are scattered across the fern, adding realism to the natural setting. The image is extremely sharp, especially at the center where the body is in crisp focus, while the legs and edges show a slight blur from depth of field, emphasizing the central figure.

The exteriors of spider eyes are part of the exoskeleton, so can't move. But in jumping spiders, the internal parts of the large central eyes have muscles that can swivel and twist to help the spider aim its eyes from inside the head. This is a 4-frame.gif showing that internal movement. 🌿🐙🕷️👀
