Appearance<\/h4>

The Ivy Bee is a medium-sized solitary bee with a warm ginger-brown thorax and striking orange-yellow stripes on its abdomen, making it more colorful than many relatives. Females are slightly larger and fuzzier, often mistaken for small honeybees.<\/span><\/strong><\/p>\n<\/div><\/div><\/div><\/div>\n\n

Special traits<\/h4>

This bee has just one generation per year. Males appear in late August, followed by females in September, and both remain active until November. They prefer sandy or loamy soils\u2014on sunny banks, lawns, or even cliffs\u2014and often form huge nesting colonies with thousands of individual burrows.<\/p>\n<\/div><\/div><\/div><\/div>\n\n

Interesting facts<\/h4>

Highly specialized, the Ivy Bee relies almost exclusively on ivy (<\/span><\/strong>Hedera helix<\/span><\/em>) for pollen and nectar, perfectly timed with ivy\u2019s late-autumn bloom. When ivy is scarce, it may visit other Asteraceae. In the Netherlands, it was first recorded in 1997 in Maastricht and has since spread across Western Europe and beyond. It is also parasitized by the blister beetle <\/span><\/strong>Stenoria analis<\/span><\/em>, whose larvae mimic female bee pheromones to attract males\u2014a striking case of natural trickery.<\/span><\/strong><\/p>\n<\/div><\/div><\/div><\/div>\n\n

Beetotem and Beehotel<\/h1>\n<\/div><\/div>\n\n

BeeTotem & BeeHotel for the Ivy Bee<\/p>\n<\/div><\/div>\n\n

The BeeTotem for the Ivy Bee is a luxurious restaurant for powerfood. It follows circular principles: inside the tube of the BeeTotem, worms brew up nutrient-rich cocktails using the kitchen scraps provided by host families. Crawling through small holes into the soil, they dispose of this compost, giving the plants a fresh nutrient boost.<\/p>\n

<\/strong><\/p>\n

This may have two effects: the pollen and nectar gathered for bee larvae become more potent, making the young bees physically stronger and more resilient\u2014possibly leading to a healthier generation the following year. At the same time, the plants themselves radiate their signals more vividly, attracting pollinators from further away.<\/p>\n

 <\/p>\n

Since Ivy Bees nest underground, a BeeHotel for ground-nesting species has been placed nearby. Together, BeeTotem and BeeHotel form a complete habitat: food and shelter side by side.<\/p>\n

 <\/p>\n

By massively planting key Ivy species (Hedera helix arborescens<\/i> and Hedera colchica<\/i>), as well as other plants that bloom at different times and provide pollen and nectar for male Ivy Bees, a tailor-made biotope is created in the neighbourhood. Altogether, there is still much to explore.<\/p>\n<\/div><\/div>\n<\/div>\n\n

KARMAGOTCHI<\/h1>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n
\n
\n

The principles behind the Karmagotchi are derived from Tamagotchi, a tool that allows hosts to easily keep track of the current condition of plants and worms in the BeeTotem. A continuous script linked to the local weather station retrieves data on temperature and precipitation and regulates the pace from 100 to 0%.<\/p>\n

Hosts have access to this interface and after adding water or kitchen scrapings they can update all other hosts by simply clicking on the water or feed icon.<\/p>\n<\/div><\/div>\n\n
