do beetle lovers care beetle's collecting method as data too? except leps. the beetle(and other insects families) specimens finally arrive to collector's desk,but little to know the method of collecting. some beetles were collected by light trap. whereas some don't. the methods that a beetle was collected comes different ways. 1,light trap.(some lucanidae mainly be caught by this way,but some seldomlly or totally don't come to light trap) 2,day time catch: a,on the flower. b,on the tree(bottom,trunk,canopy etc.) c,flower d,picked up by lucky on the ground(on the road in foresty,on the ground of forest) ,is a essential method (caught a lot) or just by lucky(few pcs). i think thouse can be also considered as essential collecting data,not only GPS(time,name of places,elevation). the method of a specimen was collected is also a important part for data,helps collectors learn more about their behavior. especially for a 'good' species,more necessary. here's a intesting example i heard from a hunter. Auxicerus platyceps seldomlly came to light trap.the main method is to cut a incision/notch on the tree,then the 'blood' of tree came out,so the Auxicerus gather together to drik the tree 'blood'. then they were bad luck been caught.

I occassionally write what plant I find Buprestidae on, but only if I can identify the plant. If its something worthwhile I would deffinetly have the collection method written somewhere.

The collection method always goes onto the data label no matter what insect it is.
In beetles there is even more methods than the ones you described, for example pit fall traps which are more common than anything you wrote above. Other methods are searching in dung of different animals, or eclosure traps or large nets that you put on your car etc. etc..
Noting the plant a specimen has been found on is of interest too, anything that might tell something about the biology of the specimen is of importance.

There are other very useful methods,too, for example for catching Prioninae from their exit holes,if you have spotted trees of their hostplants where the infection is active and there are many exit holes.
