Occasionally, springtails attack young seedlings and may damage the roots and stems. Biology and Description The Order Collembola has two suborders easily distin- guished by their body shape. One appears linear (Figure 1), while the other appears globular (Figure 2). These suborders are further divided into families that contain the separate species. Only seven families include the 650 species in North America. Worldwide, 3,600 species have been discovered.

E-mail: [email protected] 3Zoological Institute and Museum, Ernst-Moritz-Arndt-University, Loitzer Str. 26, D-17489 Greifswald, Germany. E-mail: [email protected] Abstract The first eyeless beetle known from Baltic amber, Trechus eoanophthalmus sp. n., is described and imaged using light microscopy and X-ray micro-computed tomography. Based on external characters, the new species is most similar to spe- cies of the Palaearctic Trechus sensu stricto clade and seems to be closely related to the Baltic amber fossil T. balticus Schmidt & Faille, 2015. Due to the poor conservation of the internal parts of the body, no information on the genital char- acters can be provided. Therefore, the systematic position of this fossil within the megadiverse genus Trechus remains dubious. The occurrence of the blind and flightless T. eoanophthalmus sp. n. in the Baltic amber forests supports a previ- ous hypothesis that these forests were located in an area partly characterised by mountainous habitats with temperate cli- matic conditions. -

Millipedes and Centipedes? Millipedes and Centipedes Are Both Arthropods in the Subphylum Myriapoda Meaning Many Legs
A Teacher’s Resource Guide to Millipedes & Centipedes Compiled by Eric Gordon What are millipedes and centipedes? Millipedes and centipedes are both arthropods in the subphylum Myriapoda meaning many legs. Although related to insects or “bugs”, they are not actually insects, which generally have six legs. How can you tell the difference between millipedes and centipedes? Millipedes have two legs per body segment and are typically have a body shaped like a cylinder or rod. Centipedes have one leg per body segment and their bodies are often flat. Do millipedes really have a thousand legs? No. Millipedes do not have a thousand legs nor do all centipedes have a hundred legs despite their names. Most millipedes have from 40-400 legs with the maximum number of legs reaching 750. No centipede has exactly 100 legs (50 pairs) since centipedes always have an odd number of pairs of legs. Most centipedes have from 30- 50 legs with one order of centipedes (Geophilomorpha) always having much more legs reaching up to 350 legs. Why do millipedes and centipedes have so many legs? Millipedes and centipedes are metameric animals, meaning that their body is divided into segments most of which are completely identical. Metamerization is an important phenomenon in evolution and even humans have a remnant of former metamerization in the repeating spinal discs of our backbone. Insects are thought to have evolved from metameric animals after specializing body segments for specific functions such as the head for sensation and the thorax for locomotion. Millipedes and centipedes may be evolutionary relatives to the ancestor of insects and crustaceans. -
