Butterfly nets are often sold in toy stores, often in fanciful shapes. These insect nets are usually just that—toys with net rings that bend easily or have rough netting material that tears butterfly wings, and handles that snap. All of the insect nets Acorn Naturalists provides are field-tested for durability, from economy student nets to the professional grade entomological nets. Buying a quality butterfly net is always more economical than repeatedly buying toy butterfly nets that don't last and have netting that is coarse, rips easily and tears the scales off of butterfly wings. Acorn Naturalists also offers replacement bags for insect nets along with two sizes of sweep nets for "sweeping" fields or shrubs for insect species that cling to plants and thus are often overlooked.
