Insect populations rely on there being plant life to sustain them when they emerge each spring from hibernation.
If insects are lured to emerge by warm weather too early in the spring, they will starve and not be available as food to birds.
What is too early? It is either warm enough or it is not. If it is warm enough for insects, it is warm for plants too, and both come back to life. Otherwise both stay hibernated. The system is quite robust and proven, it was well-oiled during the last few hundreds million years.
Weather can be destructive to both insects and plants (and then animals) if it is unstable, that is, if it gets back cold after becoming warmer in spring or vice versa in autumn, but that's another problem.
It would be foolish to look for just one reason for the decline of insects and dismiss all others.
Which is exactly the problem with the title of this article: "probably linked to climate crisis".
