Castor Bean Tick (Ixodes ricinus) These arachnids are completely eyeless. Instead, they use a complex sensory system on their front legs (Haller's Organ) that detects CO2, heat, and infrared light to locate hosts.

Great to get out with @OW_Photography yesterday for some macro in the sun at Skipwith Common. Plenty of action - ruby tailed wasps, jumping spiders, robber flies, you name it. Highlight for me was this Green Tiger Beetle (Cicindela campestris).

A freshly emerged may fly with its exuvia. An exuvia is the mayflies previous exoskeleton of the nymph mayfly before it crawled out of the water and transformed. Was lucky to see them arranged like this on last weeks macro workshop. This one is actually a single shot.

23 May is @TETTRIsEU 's taxonomy appreciation day - coinciding with Carl Linnaeus' birthday. Read the @sangerinstitute blog on UK springtails and the student expert identifying them: sangerinstitute.blog/2026/03… 📸Within the blog, enjoy macro photos by photographer @TimothyJonas

If you see one of these flying, you realise it's a bee mimic, even though it doesnt look much like it on the ground
Not very often I stumble across something new nowadays but I think this Hairy Rove Beetle (Creophilus maxillosus) is a first for me.

Finally! 5 years I've been looking for Platybunus pinetorum and it somehow managed to elude me until last night - out with @OW_Photography we spotted 4 of them 🙌

Something I was diagnosed with recently #sarcoidosis It's been a rough few months and has sadly prevented any macro photography but I seem to be clearing it and looking forward to getting out this week 🤞
📆 Today is World Awareness #Sarcoidosis Day Every year on April 13th, World Sarcoidosis Awareness Day draws attention to this inflammatory disease. The day also encourages those who have this condition to support one another and educate others about living with sarcoidosis. Sarcoidosis is a multisystem inflammatory disorder of unknown cause, primarily affecting young adults worldwide. It is characterized by non-caseating granulomas, most commonly involving the lungs (bilateral hilar lymphadenopathy and reticular opacities), skin, eyes, and joints, but can affect virtually any organ including the heart, CNS, kidneys, and musculoskeletal system. Pathogenesis: It involves a dysregulated immune response with activated T-cells (often inverted CD4/CD8 ratio), granuloma formation (macrophages, epithelioid cells, giant cells, lymphocytes), B-cell hyperreactivity, hypergammaglobulinemia, and elevated TNF and ACE levels. Both genetic and environmental factors contribute. Pulmonary Sarcoidosis Management: ◦ Often asymptomatic and self-limiting; many patients experience spontaneous remission and require no treatment. ◦ Asymptomatic patients: monitor with symptoms, chest X-ray, and pulmonary function tests every 3–6 months. ◦ Symptomatic or progressive disease (stage II–III): Oral glucocorticoids (0.3–0.6 mg/kg for 4–6 weeks), followed by slow taper over 6–8 months to 10–20 mg/day. Maintenance steroids are usually not required. ◦ Steroid-sparing agents: methotrexate, azathioprine, infliximab, leflunomide, or antimalarials. ◦ End-stage lung disease: lung transplantation (requires lifelong immunosuppression). Prognosis: ◦ Generally favorable; the disease resolves spontaneously in many cases. ◦ Poor prognostic factors: extensive chest involvement, extrapulmonary disease, pulmonary hypertension. ◦ About 20% of patients develop functional impairment. ◦ Overall mortality: 3–5% (higher in untreated severe cases). ◦ Highest mortality observed in African American women over age 50.

This afternoon I managed to get a 240fps slow motion macro video of a zebra jumping spider trying to predate a fly! Was a lot of effort to get this as I’m not setting anything up, just waiting and shooting :) Taken with the Canon R5ii and 100mm L macro lens @BritishSpiders

Dropping in for dinner Can this wasp carry this large caterpillar while flying after it had incapacitated it? Nikon Z9 and Z 105mm SS1/3200 F10 ISO2500

Good news everyone! Spring is on the way. Ventured out in the cold for some New Year woodland macro and spotted this young Rilaena triangularis - a.k.a. the Spring Harvestman. You find these as adults in Spring but they're already present as juveniles.

Dear all. My @vicgoddard account has been hacked and stolen. It has been renamed twice so far but is currently the one in the picture. Please can you let people know to ignore any messages from me until I get it back. Thanks @TeacherToolkit @teacherhead @PaulGarvey4

I recognise that photo 😊
🎄 #InsectAdvent Day 23 features jumping #Bristletails! #Archaeognatha (or #Microcoryphia) are primitive, wingless insects and can leap 30mm to escape predators by flexing their abdomen. They feed mostly on algae, lichens or decaying plant material. 🔗 royensoc.co.uk/understanding…

Bark spiders are some of nature’s best engineers. They spin webs that stretch across entire rivers in Madagascar; their silk is stronger than steel—and the toughest on Earth. But only females craft the mightiest webs, according to a new study. scim.ag/3KFO6Mg @NewsfromScience
