You can tell from the context whether the insect or the car is meant. Words like 'krabbeln' (to crawl), 'fliegen' (to fly), or 'Insekt' (insect) point to the animal, while 'fahren' (to drive), 'Auto' (car), or 'VW' point to the vehicle.
Auf der Blume sitzt ein schwarzer Käfer.
There is a black beetle sitting on the flower.
To name a specific species of beetle, 'Käfer' (beetle) is often used as the second part of a compound word. The best-known examples are 'der Marienkäfer' (ladybug/ladybird) and 'der Maikäfer' (cockchafer/May beetle).
Im Garten haben wir viele Maikäfer gesehen.
We saw many cockchafers in the garden.
The VW Beetle is more than just a car; it is a symbol of the German economic miracle after the Second World War. For many Germans, it is connected with personal memories and nostalgia.
Mein Opa erzählt oft von seinem ersten Käfer, den er sich 1965 gekauft hat.
My grandpa often talks about his first Beetle, which he bought in 1965.
When the car is being referred to, the brand is often mentioned: 'VW Käfer' (VW Beetle). Typical verbs are 'einen Käfer fahren' (to drive a Beetle) or 'sich einen Käfer kaufen' (to buy oneself a Beetle).
Er träumt davon, ein altes Käfer-Cabrio zu restaurieren.
He dreams of restoring an old Beetle convertible.

'das Insekt' and 'der Käfer' belong to the same area, because a beetle is a type of insect. However, 'Insekt' is the more general term. It also includes, for example, flies, bees, or mosquitoes. 'Käfer' is more specific and refers only to insects with hard wing cases. Learners may confuse the words because beetles are often simply perceived as small insects. As a practical rule: if you do not know the exact type, 'Insekt' fits better. If it really is a beetle, 'Käfer' is more precise.

Im Garten krabbelt ein schwarzer Käfer über das Blatt.
A black beetle is crawling over the leaf in the garden.
Auf dem Fenster sitzt ein kleines Insekt, aber ich weiß nicht, was es ist.
There is a small insect sitting on the window, but I don't know what it is.
