Abstract: An insect trap (10) including a housing having a support frame (11), a skin (18) of flexible transparent or translucent material attached to and substantially covering the support frame (11) to provide a housing interior (17A) which is substantially totally exposed to sunlight. A walk through passage (16A) extends through the housing interior (17A) and a brush (33A, 37A) forms a dense curtain in the walk through passage (16A) for brushing flies off an animal passing through the housing interior (17A) in the walk through passage (16A). One or more ceiling sheets or panels (20) are located in the housing which are spaced from the flexible skin (18) to define an enclosed space (57) which functions as a heat trap for insects.
