{"product_id":"firefly-costume-tee","title":"This Is My Human Costume I'm Really A Firefly T-Shirt","description":"\u003cp\u003eFireflies - also called lightning bugs - are bioluminescent beetles in the family Lampyridae, with over 2,000 species distributed across temperate and tropical regions worldwide. Their light is produced through a chemical reaction in the abdomen involving luciferin, luciferase, oxygen, and ATP, generating cold light with near-zero heat output - one of the most efficient light-production mechanisms in biology. Different firefly species use species-specific flash patterns for mate recognition, with males typically flying and flashing while females respond from perched positions. Some species of female firefly mimic the flash patterns of other species to attract and eat the males. Firefly populations have declined significantly in many regions due to habitat loss and light pollution disrupting their communication signals. The human costume is a practical choice for navigating daylight environments where bioluminescent flash signalling would attract the wrong kind of attention.\u003c\/p\u003e\u003cp\u003eCut from 100% cotton with a ribbed knit collar that holds its shape wash after wash. Taped shoulders prevent the neckline from distorting over time, and dual side seams maintain the garment structure consistently. The firefly print is applied at high resolution so the bioluminescent abdomen detail comes through accurately and stays vivid after machine washing and tumble drying.\u003c\/p\u003e\u003cp\u003eThis tee works for firefly fans, entomology enthusiasts, bioluminescence biology readers, and anyone who finds the firefly's light efficiency one of the more elegant examples of biological chemistry in common insects. It suits casual everyday wear, outdoor events, and any situation where the firefly identity is worth confirming on a shirt.\u003c\/p\u003e\u003cp\u003eMachine wash cold and tumble dry low. The shirt runs true to size. Durable enough for regular use without fading.\u003c\/p\u003e\u003cp\u003eOrder yours and confirm the firefly identity today.\u003c\/p\u003e","brand":"Gooddszeei","offers":[{"title":"Black \/ Unisex
