What problems should we pay attention to when doing insect experiments under a magnifying glass?

What problems should be paid attention to when doing insect experiments under a magnifying glass? The relevant information is as follows.

Enthusiasts pour out their hearts to answer questions, with long words (17000 words are displayed in the "My Draft" list) and many pictures (in addition to the screenshot below, there are 30 photos and two videos I took while watching insects).

Description:

Because I especially like all kinds of insects (I was interested in insects at first, because I didn't want to kill them as specimens, but I didn't choose a related major) and I am an amateur, this answer is more "wild", emphasizing how to protect insects from harm during the capture process. Friends who need to know professional practices can check other people's answers.

In this answer, besides insects, other "not insects but like insects" animals will also be involved, such as spiders and Ma Lu.

Ben answered that all the pictures and videos were taken by me while watching insects, and my photography skills were poor. Please forgive me.

This article was also published in my other official WeChat account "Insect Fun" (this is the first article in the official WeChat account), and friends interested in various insects are welcome to pay attention.

Can ask such a question, should not study related majors (or just read textbooks), so non-professionals in daily life to catch bugs generally only four purposes:

Catch it as a pet;

To raise other animals, we should catch insects as feed;

There are bugs entering the residence, and for some reason they don't want to be killed, hoping to be caught and released;

Make specimens (non-professionals should not do so much, so put them in the last item).

In view of these four situations, briefly say two words "Notes for Amateurs to Catch Insects" (because the topic doesn't seem to be a professional, I don't want to talk about professional means and necessary equipment such as lighting/food/pheromone trapping, and I don't want to talk about catching aquatic insects, in case someone drowns after watching the insects in the water).

First, the basic principle of catching insects

This is mainly two, one is to protect their own safety, and the other is to protect the safety and survival of insects.

(1) Insect catching is generally carried out in the wild. It is necessary to know the local topography, vegetation and climate in advance, and put on appropriate clothes, pants, shoes and socks to avoid injuries caused by falling, prickly branches, natural disasters, poisonous snakes and insects.
