Entomobryomorph Collembola
Entomobryomorph springtails have obviously segmented bodies in which the three segments of the thorax and the six of the abdomen are clearly visible (Fig 1, 21-18A). The prothorax (first thoracic segment) is small and lacks a pronotum so that the animal appears to have an obvious neck. The legs are long and the furcula is well developed. The body often bears tufts of setae or microscopic scales. The antennae are long and the eyes are well developed. Entomobryomorphs are characteristic of forest leaf litter. This exercise is written specifically for entomobryomorph collembolans. Tomocerus and Entomobrya are examples.
