Nội dung

MÔI TRƯỜNG, hay Khoa học về Côn trùng, liên quan đến rất nhiều sinh vật sống, một số trong đó chúng ta nhìn thấy xung quanh chúng ta mỗi ngày trong cuộc sống. Chúng có số lượng nhiều hơn bất kỳ nhóm động vật nào khác, với khoảng 12.000 loại khác nhau được biết đến để sống ở Anh, mặc dù các nhóm nhỏ hơn và kém hấp dẫn hơn hiện tại rất chưa được biết đến; và ít nhất hai mươi số lần này được biết là được tìm thấy trong các phần khác của thế giới. Nhưng để có được kiến ​​thức chung về côn trùng Anh, không có nghĩa là cần thiết để làm quen với mỗi một trong số 12.000 loài này; vì họ đã bị chia rẽ thành các phần, sao cho mỗi loài riêng lẻ có thể được xác định và sự tương đồng của nó với những người giống như họ nhận thấy nhất, và sự khác biệt của nó đã chỉ ra. Khi bạn đã có được một ý tưởng chung về các phần khác nhau của côn trùng, sau đó bạn có thể chọn nhóm mà bạn thích nhất và giới hạn sự chú ý của bạn vào nó; nhưng hầu hết con người, khi họ bắt đầu thu thập côn trùng, thu thập mọi thứ theo cách của họ, cho đến khi họ hình thành sở thích đặc biệt này.

Butinordertoobtaina generalknowledge ofBritish insects,

it is by no means necessaryto make yourself acquainted with

everyoneof these 12,000 species; fortheyhave been divided
