. An introduction to zoology, with directions for practical work (invertebrates). Fig. 192.—Male Beetle with wings outspread. (Slightly enlarged.) projecting downwards from the last as an extra foot. The Glow-worm Beetle {Lampyris nodiluca) is **B^tTeT" '^ ^'"^^^ beetle about a third of an inch long, noted for the intermittent luminous glow given out from the under side of the tip of the abdomen. This characteristic is specially notice- able in the wing- less, dark-coloured females, and prob- ably it is of use in attracting their mates. The male beetle is winged and flies well; it is a little smaller than the female, and is only very slightly luminous. Both the egg and the larva also exhibit a very faint glow. The larva is very like the female in form, but is slightly narrower, and has a row of light marks down each side of the back (Fig. 193). This beetle is only active at night, and is most usually to be found on a damp grassy bank. It should be encouraged in gardens, for the larvae eat small snails. The European Fire- flies are closely allied to our glow - worms. In them the males also are brightly luminous and go about in swarms, adding a great charm to the summer nights. The females of this fire-fly are said to be very rarely seen. The ravages of the Furniture Beetle (Anobiwm tore Beetle striatum) are only too well known, for it is the cause of " worm-eaten " wood, the " worm " being the little white larva, which, with the aid of a'pin, can some- times be extracted without difficulty from a hole in an old.
