	The funnel was first described by in the early 20th century by Italian entomologist, Antonio Berlese. He formed the idea by surrounding a metal funnel in a water jacket heated by a Bunsen burner. The heat from the water drove the arthropods down the funnel into a collection tube. Many modifications were taken upon the invention such as one by Anton Krausse, who decided to put the water jacket only on the top of the funnel. This reduced weight and drove to fauna down into the apparatus. This was later notably developed by arachnologist Albert Tullgren who decided to use an electric lamp to heat the surface of the soil instead of a water jacket.

	The funnel method is non-specific and you will catch many different species of different sizes.		The funnel method is non-specific and you will catch many different species of different sizes.
	The fault of the Berlese-Tullgren funnel is that high mortality rates tend to occur due to the direct heat and slow movements of the arthropods. however, the funnel is much faster and more efficient than other methods such as the Winkler Extractor. <ref> “Invertebrate Capture Techniques - Chapter 6.” Consult-Eco, https://stevemcwilliam.co.uk/entomol/invcapt6.htm.
