    observation

    Caught her on the pavement after the flight, wings still on. Into a test tube with water behind cotton, in a dark cupboard.

  2. 13-07-2025 21:28

    observation

    Wings off. She has walled herself in behind the cotton plug, so from here it is hands off until there are workers.

  3. 17-07-2025 22:13

    eggs

    First eggs — a clutch of about ten, tucked under her head.

  4. 05-08-2025 20:18

    larvae

    Larvae. The clutch has turned into a slowly moving pile.

  5. 24-08-2025 21:02

    pupae

    Pupae, pale and stiff. Egg to worker takes six to eight weeks at 24 °C, so this is on schedule.

  6. 09-09-2025 19:19

    new workers

    Three nanitics. The first workers are always undersized — she fed them from her own flight muscles.

  7. 11-09-2025 22:27

    feeding

    First feeding: a drop of honey water on foil. Two of them found it within the hour.

  8. 15-09-2025 18:05

    feeding

    Honey water and half a mealworm. The worm was stripped by morning.

  9. 20-09-2025 20:44

    observation

    The second batch of eggs is bigger than the first. She is being fed now, so that makes sense.

  10. 21-09-2025 17:37

    hydration

    Refilled the water reservoir.

  11. 21-09-2025 19:28

    feeding

    Fruit fly, freshly killed. Carried in whole.

  12. 25-09-2025 20:17

    feeding

    Sugar water on cotton. Three of them stayed on it for an hour.

  13. 26-09-2025 22:39

    cleaning

    Cleared the rubbish heap and wiped the outworld.

  14. 29-09-2025 19:51

    feeding

    Two small mealworms; one went straight to the brood chamber.

  15. 01-10-2025 17:35

    hydration

    Damp end was drying out; topped it up through the side hole.

  16. 03-10-2025 22:06

    feeding

    Cricket leg. Too big, in hindsight — half of it ended up on the heap.

  17. 08-10-2025 20:16

    feeding

    Honey water. Quiet feeding, most of them stayed inside.

  18. 10-10-2025 19:14

    cleaning

    Outworld cleaned; leftovers were starting to smell.

  19. 11-10-2025 17:45

    hydration

    Water reservoir refilled and the sponge in the outworld rinsed.

  20. 12-10-2025 17:24

    feeding

    Mealworm, cut open. That gets eaten twice as fast as a whole one.

  21. 12-10-2025 17:55

    new workers

    The second batch has hatched. The tube is starting to look busy.

  22. 16-10-2025 17:41

    feeding

    Fruit flies from the culture. Four went in, none came out.

  23. 20-10-2025 22:35

    feeding

    Sugar water and a drop of protein jelly. The jelly was ignored again.

  24. 21-10-2025 17:29

    hydration

    Small refill. The nest holds moisture better since the cover went on.

  25. 25-10-2025 21:58

    feeding

    Mealworm. Trail across the outworld within minutes this time.

  26. 26-10-2025 18:57

    cleaning

    Rubbish heap out, glass wiped, escape barrier re-oiled.

  27. 29-10-2025 21:43

    hydration

    Refilled the water reservoir.

  28. 31-10-2025 20:42

    feeding

    Honey water and half a mealworm. The worm was stripped by morning.

  29. 01-11-2025 22:49

    observation

    Into the wine cooler at 8 °C for the winter. No food, just a damp sponge and the dark.

  30. 20-02-2026 20:46

    observation

    Out of the cooler. Slow for about a week, and then everything at once: eggs within days.

  31. 25-02-2026 21:18

    feeding

    Fruit fly, freshly killed. Carried in whole.

  32. 01-03-2026 18:09

    feeding

    Sugar water on cotton. Three of them stayed on it for an hour.

  33. 01-03-2026 18:27

    hydration

    Damp end was drying out; topped it up through the side hole.

  34. 01-03-2026 22:50

    cleaning

    Cleaned out the remains of last week's mealworms.

  35. 07-03-2026 20:32

    moving

    Moved them into a small Ytong nest, one damp end and one dry. Left the tube connected; the brood was carried over in two days.

  36. 08-03-2026 18:46

    feeding

    Two small mealworms; one went straight to the brood chamber.

  37. 11-03-2026 22:34

    hydration

    Water reservoir refilled and the sponge in the outworld rinsed.

  38. 14-03-2026 18:44

    feeding

    Cricket leg. Too big, in hindsight — half of it ended up on the heap.

  39. 17-03-2026 20:07

    Cleared the rubbish heap and wiped the outworld.

  40. 20-03-2026 17:44

    feeding

    Honey water. Quiet feeding, most of them stayed inside.

  41. 20-03-2026 20:11

    hydration

    Small refill. The nest holds moisture better since the cover went on.

  42. 25-03-2026 18:05

    new workers

    Counted about 12 workers. The nest is filling up faster than it did last month.

  43. 26-03-2026 18:04

    feeding

    Mealworm, cut open. That gets eaten twice as fast as a whole one.

  44. 29-03-2026 18:00

    hydration

    Refilled the water reservoir.

  45. 29-03-2026 21:09

    observation

    They have picked the damp chamber for the brood and turned the dry one into a rubbish heap. Exactly the way the guide says.

  46. 31-03-2026 17:54

    feeding

    Fruit flies from the culture. Four went in, none came out.

  47. 31-03-2026 18:13
