** Two disadvantages not contribute

A first drawback is clean gender: 2500 insects of all: we must make choices: some comments show: not everything can be included.

The second drawback is the fact that the existence of sub species is not clearly mentioned. While it is clear that the number of species of the family or genus, ie the relativity of insects presented, the author presents an insect drawing, it identifies, but without indicating how many other species or sub variants exist. So the beginner or amateur recognizing a generalist insect will be led pronnoncer too precise identification too quickly, without even knowing that there are alternatives.
For example the very common Graphosoma bugs: only Italicum is made, or it is a subspecies, there are another: lineatum distinguished by the red of one of his legs, and another species which punctatum pronotum not consitutes lines. This is the first insect that I sought to identify. Conclusion: even we recognize the pattern of the insect, systematically check from a more comprehensive source.

A review

It would not have much more room to include some criteria for distinction between close species at least for the most common since this is the purpose of this book is to serve as a guide.

** These disadvantages and the criticism does not question the value of the work, especially once warned these limits.

Solid, compact enough spaces for communication includes annotations, many comments have work as a field book.
However the notion of field work does not have much sense: the insect will not wait to be identified, and such a book is too general to get out in nature without other resources.
The approach is to rather make use of a digital camera and then check online.
So you could do without such works, especially since it is invetaire sites of insects by geographical areas or habitats.

The book will be recommended
- For children, teens, anyone who does not have extensive use of digital cameras and the Internet.
- To build up a base of the most common species, as and when consultations. Starting with check in Chinery, passing the same page, the same images, we manage to memorize the insects it presents, ie an already substantial base.

Note that there are cooperative inventories of butterflies, bumblebees, etc. that allow scientists to exploit the data you collect through this book.
