It is not uncommon to find weakened bumblebees on the ground in spring.While finding weakened bumblebees on the ground can be worrying, we can help them by providing them with some rest and food and protecting them, if necessary, from dangers such as predators. With a little care and attention, we can support weakened bumblebees and help them find their way back to health and vitality.

Causes of weakened bumblebee

  • Winter hardships : During the winter period, bumblebees are inactive and spend the time in a resting phase, known as diapause. Although bumblebees are in this condition, some cannot survive due to various factors such as cold temperatures, food shortages, or diseases. As a result, weakened bumblebees that have survived the winter may emerge in spring and have trouble getting their energy back.
  • Food shortage : In early spring, bumblebees can sometimes have trouble finding sufficient food sources, especially when flowers are not yet fully blooming. As a result, they can become weakened due to a lack of nutrients and energy.
  • Parasites and diseases : Some bumblebees may be weakened in spring by parasites such as mites, which may have spread in the nest during the winter period. These parasites can affect the health of bumblebees and impair their ability to survive.
  • Old age : Bumblebees generally have a shorter lifespan than honeybees, and as they age, they can become weaker and less energetic. Old bumblebees may become exhausted in the spring and have trouble returning to their nests.
  • Extreme weather conditions : Unpredictable spring weather conditions, such as sudden changes in temperature or heavy rainfall, can confuse bumblebees and make their search for food difficult, leaving them weakened and disoriented.
