Discovering insects in the garden: Five species in midsummer

Key points at a glance

• Many insect species in your garden often go unnoticed due to their small size or hidden way of life.
• Species such as the common red soldier beetle (Cantharis livida) or the Saxon wasp (Dolichovespula saxonica) fulfil important ecological niches as predators and pollinators.
• Deadwood and native wild plants like dock species (Rumex) are the crucial foundation for the survival of these specialised insects.
• Observation requires patience: linger in one spot for a few minutes to understand the complex interplay between species.

Why July is crucial for observations

In midsummer, insect activity reaches its peak. Many species that we overlook in the spring are now active as imagines (adult insects), foraging for food or breeding. An ecologically valuable garden offers a mosaic of different habitats during this time – from sunny, nutrient-poor sites to shady deadwood areas – which is what makes this diversity possible in the first place.

By focusing your attention on these "overlooked" creatures, you will develop a better understanding of biological regulation in your garden. Predatory insects keep populations of aphids and other pests in check, while specialised flower visitors ensure pollination, even if they don't enjoy the same fame as honeybees.

The following overview shows you five species that often live right on your doorstep but are rarely consciously noticed. Look out for these characteristics during your next walk:

How to observe correctly

To discover the hidden biodiversity in your garden, a systematic approach helps:

1. Choose your location: Look specifically for umbellifers like wild carrot (Daucus carota). These serve as a landing pad for many beetles, such as the common red soldier beetle (Cantharis livida).
2. Be patient: Stay at a wildflower strip for at least five minutes. Many insects only move once they feel safe.
3. Integrate deadwood: Leave old wood lying around. The four-banded longhorn beetle (Stenurella melanura) relies on deadwood as a breeding site.
4. Make use of twilight: Observe your garden shortly before sunset. This is when the full activity of moths like the small fan-footed wave (Idaea biselata) is revealed.
5. Know your plants: Keep an eye out for dock species (Rumex). These are essential as egg-laying sites for the small copper (Lycaena phlaeas).

Frequently asked questions

Why is the Saxon wasp useful for the garden?

The Saxon wasp hunts insects and caterpillars to feed its larvae, thereby contributing to natural pest control.

What do the larvae of the four-banded longhorn beetle need?

The larvae develop in decaying wood over several years. Deadwood is therefore an essential habitat for these beetles.
