The First Bumblebee of the Year
Today's most exciting encounter was with, what I call, the 'Panda' of the insect world. Well, to be honest, I had two exciting finds today, but I'll keep the second one for tomorrow, since I feel it deserves its own post.
Today I met a Buff-tailed Bumblebee (Bombus terrestris). It was doing exactly what bumblebees do best: looking slightly confused while vibrating at a very high frequency.
If you ask anyone to draw a 'friendly' insect, they usually draw either a butterfly, or a bumblebee. Bumblebees are big, fluffy, and they move with a heavy, stumbling gait that makes them seem harmless. They don't have the sleek, predatory look of a wasp or the frantic energy of a honeybee. They just sort of bumble along.
Seeing one in early March in Hungary is a very serious survival story unfolding.
The Lone Survivor
Right now, every large bumblebee you see is a Queen.
Unlike honeybees, who stay in a hive all winter eating stored honey, the bumblebee colony doesn't survive the frost. Last year’s workers, drones, and the old Queen are all dead. This female is the only one who made it. She spent the winter buried in a hole in the ground, her metabolism slowed to almost nothing, waiting for the earth to hit the right temperature.
She is a one-woman startup. She is the CEO, the architect, and the labor force. Inside her, she carries the eggs for an entire future colony. If she gets hit by a car, gets eaten by a bird, or simply runs out of energy today, that whole family tree stops.
Warming Up the Engine
One of the most interesting things about seeing them this early is how they can handle the cold. It’s currently around 10°C or 12°C during the day, as low as 2°C at night, which is still too cold for most insects to move.
The bumblebee has a 'brute force' solution. She uncouples her wings from her flight muscles and vibrates them internally. If you find one sitting on a flower and hear a low, angry-sounding hum, she isn't threatening you; she’s 'shivering' to warm up.
She has to get her internal temperature up to about 30°C before she can take off. It’s like trying to start a cold diesel motor in the morning. It takes a lot of fuel (nectar) just to get the engine running. If she spends more energy warming up than she finds in the few flowers currently blooming, she won't make it.
The Real Estate Agent
I found her crawling over a patch of bare earth near the edge of the vineyard. She wasn't looking for food; she was looking for a house.
Buff-tailed bumblebees are famous 'squatters'. They don't build nests from scratch like wasps or honeybees. They look for abandoned mouse holes or tunnels. They want a pre-dug, insulated cave where they can start building their first wax pots.
When you see a bumblebee 'bumbling' along the ground, she isn't lost. She’s surveying. She’s checking every crack and shadow. She’ll crawl into a hole, stay for a minute to check the 'vibe', and then pop back out to try the next one.
Why the 'Panda' Matters
I call them the 'Pandas' because they are the 'gateway' insect. They are the ones that get people to care about the garden. You can’t really 'love' a tick or a horsefly, but it’s easy to love a big, fuzzy ball that looks like it needs a hug. Ask someone not to pull the dandelion out of the lawn because it attracts nice hoverflies, and they rarely care. But tell them it's vital for the bumblebees, and you have a decent chance that they will leave it for a couple days longer.
But being a Panda in the wild is hard work.
In my garden, these are the residents I watch most closely. Because the Queen is alone right now, she is incredibly vulnerable. If I tidy up the garden too much, if I fill in every 'messy' hole or pull every 'weed', I am essentially destroying her housing and food options.
The Observation
I watched her for about ten minutes. She investigated three different holes under some dry grass, decided none of them were quite right, and then spent another five minutes just sitting on a sun-warmed stone to recharge.
When you sit still, you see the effort. You hear the engine warming up. You see the queen of a future kingdom looking for a place to start.
She eventually found a gap under an old vine root and disappeared inside. I didn't see her come back out. Maybe she found her home.
