| Various bee species, including honey bees, store food to ensure the survival of the entire colony in times of food shortage (winter, the rainy season in the tropics). During the winter a beehive needs to maintain a minimum temperature of 10 degrees Celsius, otherwise the entire colony would die. The food stock of bees (honey) is edible even at very low temperatures. | | |
| | Nematocera | | Nematocera belong to the Insect Order Diptera. Examples of Nematocera families are: Anisopodidae, Bibionidae, winter crane flies, crane flies, net-winged midges, blackfly, gall midges, biting midgets, dark-winged fungus gnats, minute black scavenger flies, phantom midges, phantom crane Flies, Chironomidae, moth flies, mosquitoes, Macroceridae, and fungus gnats.

| | | The adult insects reach a length of 12 to 15 mm. They are green-brown to bronze in colour. However after the winter, their colouration is light green. Their bodies are covered in small dimples and spots, their feet are brownish in colour, and the outer edges of their wing covers are yellowish. | | |

| | ...or the fertilization of young queens. To avoid inbreeding, some drones leave the nest and look for females from other populations.
While the old queens usually die in the autumn the young fertilized queens seek safe homes. With the cold of coming winter huge numbers of worker wasps die from starvation and as a result many colony wasps become solitary. In spring new colonies emerge from the overwintering young queens.
Wasps have a smooth sting which they use to inject crippling substances into their prey and to defend themselves (even by spraying poison) and this sting can be used again and again. The Honey Buzzard and the Ichneumon wasp are ... | | |
| | Adult drone flies are active from March to October. As the female drone flies overwinter, they also can be encountered outdoors on warm winter days. | | |
| | Chrysoperla camea s. l. | | ...ysoperla camea s. l. reach wing spans of between 15 and 30 mm. Their bodies are long, slender and green in colour. Their wings have thick veins. They have compound eyes which glitter and are bright and clear. Some types turn brown before the winter. Chrysoperla camea s. l. reproduce several times a year. The adult insects are usually active at twilight and feed on pollen, nectar and honeydew from aphids. During the day they sit, hidden, under leaves. They overwinter in places where they are well hidden from other animals and insects. Their larvae are considered beneficial as they eat aphids (up to 10 per day) and aphids are viewed as pests in agriculture . In 1999, the Chrysoperla camea s. l. was declared... | | |

The adult spider can be encountered from high summer to late autumn. The eggs (laid by the female) survive the winter in a cocoon. The young spiders hatch in the spring. | | |
| | Lagriinae | | ...ike brown wool.
Lagriinae eat young leaves of flowering plants. They are encountered on grasses, herbs and shrubs. The adults fly throughout the summer. The larvae of Lagriinae are white and brownish in colour. They are very small and survive the winter on fallen leaves, which are also their food source. The larvae turn to pupae in the soil. | | |
| The fertilized queens overwinter and appear again in the spring. In May, they start nesting, mostly in bushes, but also on rock faces or house walls. They do not nest in dark cavities. The nest is made from a paper-like material, mostly won made of poplar bark. The nest includes br...
...ood supplies for the larvae is their responsibility. A colony can accommodate as many as 200 wasps. The nest can grow to approximately the size of a football. In August additional males and young queens are bred. The young fertilized queens seek out winter hideouts, while all the other wasps die. | | |
