When a bumblebee nest is first established by a queen, she is responsible for all the tasks. She will forage for nectar and pollen, build the nest, incubate her eggs, and feed her first brood. Once the first workers hatch, they will take over most of the foraging, nest maintenance, and brood care, allowing the queen to focus on laying eggs.

How long will it take for the mother to return if she fancies the nesting site
The time it takes for the queen to first return to a suitable hive is dependent on the degree of their biological maturity for nesting.
It could be, for example, 20 minutes, but also several days. Apart from her maturity (readiness to nest) depends on weather. If the mother likes the nesting site, but immediately strongly cools, He'll be back after it warms up., feel free to leave it for more than 7 days.
Breeders sometimes they are making a mistake that after a long absence of the queen in the nest doesn't believe in her return and they'll move in the new queen. After some time, however, the original will return and arise The risk of an unwanted collision on both.
When does a mother start building a nest
If the conditions are good and the mother is hormonally prepared, essentially as soon as the nesting site is discovered it begins with nest building. This can be a matter of minutes, hours, or even days.
Sometimes a mother just inspects the nest but doesn't start nesting – she doesn't have developed ovaries and needs to be supplemented and the eggs to mature. There is no need to settle down and then just wait. Everything in the life of bees has its time and purpose, there is no time for trivialities.
Sometimes a mother knows the arrival of cold days, and so she as soon as it nests, although she made a beautiful orientation flight. She liked the place, however, and sometimes returns to it to make sure it is still „free“ and that she can move in.
Example 1
From personal observations (end of March 2020), we know that a buff-tailed bumblebee mother (B. terrestris) was introduced into a hive. After 25 minutes, she made a orientation flight, returned to the hive after 10 minutes, and after another 5 minutes, she began carrying nectar and ivy leaf juice into the hive to reinforce the chamber walls.
Example 2
The mother bumblebee (B. ruderatus) performed a bland, uninspiring orientation flight after settling and then flew away. After a week of cold days with temperatures near zero (March 2020), she reappeared on her own and began to build a nest.

What does the mother actually do in the nest
After marking with its pheromones, the queen in cotton wool filling will create a small spherical nesting chamber. Her walls reinforced with nectar, sky juice from plants. Then it begins to bring pollen pellets to the bottom of the chamber. It then moistens these with nectar and compacts them with its mandibles into a flat structure.
Formed cover the flat surface with a thin layer of wax. The queen bee excretes between the abdominal segments and wipes her legs. She also in her nest dust and shape it Pollen bun.
The building of this part of the nest can be completed by the mother by 3-5 days, but under good conditions also to 2 days.
From this, it will form on the surface of the pollen case, into which the publisher eggs a closing of the bid.
At some point during this time, the mother will begin to also perpetual nightt – must care for the offspring and keep it warm.

How about egg-laying?
Number of eggs varies depending on the species of bumblebee and the amount of food. According to J. Čížek's observations, it can be determined in the range 4 -20 eggs.
Time from nest establishment to layingcan also vary. A queen can lay as early as the day of founding (if she has a nest prepared), but also as late as the 4th day from founding the nest.
Usually beforehand, but sometimes also during the incubation of eggs, the queen at the entrance to the nesting chamber Create a nectar pot from wax. In times of food surplus, it will also create more food chambers. Sometimes, however, nest building begins with the preparation of food stores. In this way, it instinctively prepares for possible weather fluctuations. A food supply will allow it to spend more time in the nest. Therefore at the start, the mother flies so often and afterwards it is difficult for her to be seen.
Mother often her warmed by the body heat of the egg in its shell and maintains them in optimal conditions necessary for the successful development of the foetus.
A mother can flapping of flight muscles convert energy from nectar to heat to carry it contactually with its bare belly to the foetus hidden in a waxy casing.
Between the wings and the flight muscles, it has a kind of coupling. It „flies“ somewhat at a leisurely pace. Thanks to this, it can to warm up the embryo and the small nest chamber to 30°C. But this has its limits, see HERE
The chamber is just big enough for the mother to fit inside, along with her offspring. The mother must conserve energy, which is why her chamber is also very cramped. Everything serves a purpose – in cold weather successfully To raise a crop.
After 3 – 5 days after laying (depending on the type of bumblebee), larvae hatch chucks. The queen bee herself brings food and feeds the larvae.
How bumblebees feed their larvae
Are known two types feeding bumblebee larvae
feeding by storing pollen loads in holes under the larval case, so-called. pollen sacsThe larvae feed themselves from below, so they can be fed even when the mother is away from the nest.
2) feeding through openings in a waxen wrapping covering the larvae. The queen creates an opening in the middle of a coiled larva covered with a thin layer of wax. Into this, she secretes a small amount of food and initially immediately closes the opening. For mature larvae, however, which distinguish themselves into separate waxen cocoons, the opening is left unclosed for the entire duration of the larvae's growth.
According to these two types, bee species can be divided into two groups:
1) Pocketmakers, who do not store honey in empty combs, but in wax cells.
An example of such a bumblebee is the common carder bee (Bombus pascuorum).
2) Spollen keepers The larvae are fed using openings in the wax casing. They store this pollen in empty cocoons of already hatched bumblebees. They stuff the pollen into them, similar to how bees do, and treat it so it doesn't dry out.
An example of such a bumblebee is the buff-tailed bumblebee (Bombus terrestris)
However, as is usually the case in nature, under certain circumstances bumblebees do not respect the division established by humans, and they use more or less both types of feeding.
Note:
- It is quite difficult to provide supplementary pollen to bumblebees of the pocketmakers group. The larvae take it from their pockets, and if a worker or queen finds it elsewhere, they are unable to carry it back to the pockets – in the best case, they consume it themselves.
- For groups of pollen storers, pollen can be provided to bumblebees, for example, in a PET bottle cap. If it is located near other feeders, the queen/workers can use it to feed the larvae. Otherwise they consume it themselves.

How long do the larvae feed for when the first workers appear in the nest
Era from the hatching of larvae from eggs to their pupation It depends on the temperature in the nest and the amount of food supplied., as well as the mother's strength and other conditions. It usually moves with Around 8 days.
The hatching of workers after their pupation then ends Solitary phase Queen bees and the development of a bumblebee nest.
Its length, which varies between species, can be determined within the range From 18 days to 1 month.

Why does Mother fly irregularly
Does he really have „full wings of work“. It must build wax comb, heat the brood, feed the larvae, open and close the wax cell with larvae for feeding. On top of that, it must fly out for nectar and pollen and so on and so forth.
This is how it's done throughout the solitaire phase – until the birth of the first workers.
All this time the mother flies very irregularly. It doesn't stop – it first works on building its nest. It only flies out when it needs nectar for construction or as food for itself – the same goes for pollen.
Initially, the bee needs little to create a flattened area (a pad) under the wax cell and to create a supply (a pollen ball). She feeds on pollen herself – she needs protein for her eggs to mature within her.
If the mother has a brood and food supplies in the hive, will fly Come on, at least a little – doesn't need it and doesn't have time for it.
If we were to give the queen all her food (nectar and pollen) in her nest, she wouldn't fly at all. It's important to realise that the purpose of life isn't to flit around flowers, but to establish a new generation of queens and males – this is the goal of their lives. Therefore, bumblebees can be reared in a laboratory in a plastic box without ever seeing a real flower or the sun.
The intervals between flybys are varied and this often greatly troubles new breeders. They so wanted to see the queen flying and then suddenly they can't see her at all. Mostly they have a problem accepting that it's up to the queen and that she will be flying according to its „schedule“.
What really bothers users is that one day the mother is flying „a lot“, and then suddenly „she" It behaves strangely and flies little“It is a useless torment of oneself and a human perspective. It is necessary to come to terms with the fact that The mother does not respect the breeder's interest, but her own needs and those of her future family..
Very often The fears of breeders lead to interventions in the nest, and its subsequent damage and destruction.. She also tries in various ways to stimulate, feed and persuade the mother in the beehive „to have cocoons already“.
Very often, they don’t stick with it and bring another queen into the hive without being absolutely certain that the original queen is irretrievably lost – they don’t give her a chance or the time to prove to them that everything is fine. This is all wrong.
Each year, in a similar situation and after a cold spell, we encounter cases where an impatient beekeeper opens a bait hive and searches for the nesting chamber within.„for him to see his mother„If anything, a mother in early nesting hurt, So it's an event.
The mother is very sensitive in the solitary phase. Very often leaves the nest and it becomes a so-called firefly.. He doesn't have to leave it just because of a disturbance. Ransacking a nest leads to the destruction of the structure. The delicate goblet of nectar spills, the chamber ceiling tears, and any eggs in the wax casing are smashed.
How to find out if the mother is in the nest
Observation
The breeder can observe the startle and watch the movement on the palate, that is the best method, but unrealistic. Likewise, it may happen that the breeding mother barely sees – glides past him He won't even notice. Alternately, he sees a figure at the ulcer and he will not return to it and waits in the distance
Mark in the entry hole
The practical solution is to use a marker in the entry hole, see HERE
No brand is a perfect solution. A beginner often places the brand incorrectly, and the mother bee bypasses it (but this can also happen with an experienced beekeeper).
Therefore, we recommend place the tag repeatedly and reduce the risk that the mother will pass it and not nurse it.
The mother in the hive will respond to a gentle tap.
If the queen bee is present (preferably at night) and is in the nest, it's possible to detect her presence by gently tapping the wall of the hive. The queen will respond with a distinct, threatening buzz – she is defending the nest against a perceived intruder.
This method has Restrictions:
- A hen that does not yet have anything to defend (has not laid eggs) will not make a sound.
- the mother, who has a cold, speaks in an almost inaudible whisper
- the mother of some smaller species (for example, the mother of a field bumblebee) is practically never heard
Electronic sensors
Newly Electronic sensors have begun to be used. These sensors in the corridor monitor and count the passages of hoverflies.
We'll see how these devices do. It's about, how to cope with the conditions in the hive (warmth, humidity) and whether the bumblebees are not polluted by dirt in the passageway.
Trail cameras
There are a number of camera traps that react to movement near the entrance hole and, whilst producing low-quality images, still provide documentary shots. Such traps are often Constructed with climate conditions in mind. However, quality traps are quite expensive.
Mobile phone
As an alternative to a trail camera, you can also use an older mobile phone and a suitable app. However, the disadvantage is Poorer durability such a device weather-resistant.
What to do if the breeder doesn't see the mother
This is one of the most difficult moments of our work – explain to the breeder that everything is okay and that the queen mother pThe rust flies as it needs to, and that it misses.
They can wait for and monitor the mother's movements according to the brand, repeatedly and differently place it here.
The breeder must understand and, above all, accept, that:
- The mother cannot and It won't fly regularly
- It's no use worrying about your mother worry
- There's nothing to be done but wait. and any of the methods occasionally gently reassure that mother is present
- Do not unnecessarily look into the nest. – would unnecessarily frightened the mother and in the worst case drive her away
- Do not dig through the lining, look for a nesting chamber, or a wax comb structure – it would damage everything and drive the queen away
- There's no point and you mustn't introduce a new mother into the hive, When they hadn't seen each other for the first few days, or „she's strange because she flies little“ - the mothers would meet and one/both would die in combat.
Experiences from our advisory centre
- Experience from our advisory service tells us that usually everything is fine, and unfortunately it is problem only with an impatient owner, who simply wants to see their mother fly.
- Such an impatient breeder often unnecessarily disturbs the mother, peers into the nest, wonders what's wrong with „his“ mother, and wants to resuscitate her in every possible way.
- Sometimes it digs up the nest and destroys it permanently.
- Sometimes it feeds the mother in the hive and wonders why she is being fed at home.
- Sometimes the breeder leaves food for the mother and she just drops in for a buffet, not wanting to settle in.
- If you get a bumblebee nest, for example from „Český čmelák“, you will not see the queen at all and the bumblebees will only fly out when the food they were given for the journey runs out.
If you really need to check if the queen is in the hive, you can do this by gently tapping and listening at the ventilation hole.
For filming purposes, we removed the roof and filmed in red light so that the queen bee's response could be heard.

Conclusion
- You already know that mothers They have a lot of work in the nest and only fly out when they have to
- Mothers will not fly as you wish and You'll only see them occasionally.
- If you want to meet your mother, adapt to her and observe her from a reasonable distance. Give her your time
- Do not disturb the mother by unnecessary tapping that startles her – it's stressful for her
- Under no circumstances should you interfere with the mother's lining or even her work.
- Place your trust and time in your mother., when you settled her in at your place
- If The rash really doesn't appear even after 7-10 days, carefully check the nest, make sure it is empty before attempting to inhabit it
- Don't be stubborn and accept the possibility that even if you tried really hard, your jump will be in vain..
- It is no shame to have an empty quiver, It's a disgrace to have the dread occupy at all costs, even at the unnecessary loss of a mother's life, whom you didn't believe really lived with you, and to whom you moved in a new mother.
- If you keep your composure, The queen matka will reward you royally indeed – beautiful workers and then a generation of their successors and hunks – grooms
