  The transparent container 10 is made of glass or plastic. Here, the transparent container 10 is a bottomed container having a rectangular cylindrical body having four side walls 11 and has an opening 12 at the top.

  The moisture holding mechanism 30 is constituted by a soil placing table 33 constituted by a plate 31 and needle-like leg portions 32 and a soil holding sheet 34. The plate 31 has an area equal to the area of the bottom surface of the transparent container 10 except for a portion where the position of the water tank 20 is notched as shown in FIG. An infinite number of holes 35 for dropping water are formed.

  As shown in FIG. 3, the needle-like leg portion 32 has an area slightly narrower than the area of the bottom surface of the transparent container 10, except for a portion where a position where the water tank 20 enters is cut out. The needle-like leg portions 32 are formed by arranging innumerable lattice holes 37 by arranging square bars 36 having a required length in a lattice shape so as to be orthogonal to each other in the vertical and horizontal directions. Needle-like legs 38 extending toward the bottom surface of the transparent container 10 are provided on the back side of the intersection of the square bars 36.

  Needle-like legs 32 are disposed on the bottom surface of the transparent container 10, and the plate 31 is placed thereon. The soil holding sheet 34 is a net-like sheet having a fine mesh, and is configured to be able to hold soil containing a certain amount of moisture and to drop excess water. The soil holding sheet 34 has a notch 39 so that the part of the water tank 20 is hung from the needle-like leg 32 and the notch of the plate 31 and is placed on the bottom surface of the transparent container 10.

  As shown in FIG. 4 and FIG. 5, which is a cross-sectional view of the main part thereof, the water tank 20 disposed in the notch portion of the needle-like leg portion 32 and the plate 31 is a transparent container made of plastic, for example, and includes a moisture holding mechanism 30. It has a height dimension such that the opening 21 side protrudes beyond the soil 41 placed almost flat on the top of the. For example, those having a length of about 150 mm, a width of 100 mm, and a height of about 100 mm are used. When the tank 20 is filled with about 80 to 100 mm, it is possible to put up to 50 larvae at the maximum in Heike fireflies and about 20 in Genji fireflies.

  A pair of opening sides of the water tank 20 is provided with an inverted L-shaped guide 22 for sliding the water tank lid 25 at the opening 21. The aquarium lid 25 is provided to detachably cover the opening 21 of the aquarium 20 and is provided with a plurality of through holes 26 for use during spawning after the emergence of fireflies.

  The firefly breeding / observation apparatus is provided with a passage plate 28 constituting an inclined passage. The passage plate 28 has substantially the same shape as the opening 21 of the water tank 20 and has a longer side than the two sides on which the guides 22 are provided. The passage plate 28 is detachably stood on one side of the opening 21 of the aquarium 20, and is used so that one side abuts against the bottom and side corners of the aquarium 20. Provide a passage for fireflies to reach the final larvae. For this reason, the surface side of the passage plate 28 is a non-slip processed surface in which sand or the like is attached by an adhesive.

  As shown in FIG. 6, the light shielding plate 15 surrounds the four side walls 11 of the transparent container 10 corresponding to the positions where the soil 41 is spread, and at least a part of the light shielding plate 15 is detachable. Here, the light shielding plate 15 is a rectangular elongated plate made of a resin such as black plastic or paper, and is all pressed against the four side walls 11 of the transparent container 10 by an elastic ring-shaped strip 16. . For this reason, it is possible to remove the desired position or all the light shielding plates 15 from the band 16 and observe the firefly last-instar larvae and pupae that have entered the soil 41. Of course, the light shielding plate 15 may be provided with a frame for moving the side wall 11 of the transparent container 10 in the vertical direction at the joint portion of the side plate of the transparent container 10 so that the light shielding plate 15 can be attached and detached. Further, a hinge may be provided at the joint portion of the side wall 11 of the transparent container 10, and the light shielding plate 15 may be configured to be detachable by rotation.

  As shown in FIG. 6, the container lid 18 closes the upper opening 21 of the transparent container 10, and can be constituted by, for example, a plastic net that is three-dimensionally sewn so as to hang from the opening 21 toward the side wall 11. . An elastic string 19 that wraps around the edge is sewn on the edge of the container lid 18, and the side wall 11 of the transparent container 10 is tightly bound by the string 19, and the transparent container 10 is sealed by the container lid 18. The upper opening 12 can be tightly closed, and a configuration that prevents the escape of adult fireflies from the gap between the upper opening 12 of the transparent container 10 and the container lid 18 is adopted.

  The soil 41 has a water retention function to the extent that fireflies like red soil or sand, and is neutralized. As shown in FIGS. 4 and 5, the soil 41 is mounted on the upper part of the water retention mechanism 30 so as to be approximately flat and has a height of approximately 80 mm to 150 mm.

  The firefly breeding / observation apparatus according to the present embodiment includes a moss layer 45 serving as a spawning bed as a spawning place for fireflies, a population (for example, made of plastic) serving as a resting place for fireflies, or a natural planting 51, FIG. A spray sprayer 55 as shown in FIG. The moss 45 contains water sufficiently and is placed on the water tank lid 25 for use. Instead of the moss 45, a similar plant or fiber having water retention may be used as a spawning bed. The planting 51 is used by burying the root portion in the soil 41 at a desired position. The atomizer 55 is used for suitably holding the moisture content of the soil 41 by spraying the entire area around the soil 41 at a frequency of, for example, about 5 times a day.

  A firefly breeding / observation device is created in a state where the above-described components are appropriately arranged. Further, as shown in FIG. 9, about 20 firefly last-instar larvae 70 are enclosed in a plastic bag 61 together with water and oxygen and packed in a foamed polystyrene container 60. Of course, the water tank 20 is not filled with water. The remaining components of the firefly breeding / observation device are set in the transparent container 10 together with the polystyrene foam container 60 to be sold as a firefly breeding / observation kit as shown in FIG.

  The planting 51, the atomizer 55, and the container lid 18, and in some cases the moss 45 are not essential as a firefly breeding / observation kit, and may be prepared by the purchaser. Alternatively, the soil 41 may be separately packed in a plastic bag, and the purchaser may take it out of the plastic bag and set it at a required position.

  The purchaser puts well water or purified tap water in the aquarium 20 so that the water level is about 80 mm to 100 mm based on a breeding guide (not shown) enclosed in the kit, and the infancy larva in the plastic bag 61 Is put into the water in the water tank 20. The passage plate 28 is set in the water tank 20 containing the last-instar larvae and water, and this is arranged in the transparent container 10 as shown in FIG.

  Furthermore, the position corresponding to the soil 41 on the side wall 11 of the transparent container 10 is covered by the light shielding plate 15, and the root portion of the planting 51 is embedded and fixed in the soil 41 at the desired position, and the upper opening 12 of the transparent container 10. The container lid 18 is set to the firefly breeding observation apparatus shown in FIG.

  In the above state, the instar larvae live in the water of the water tank 20 without taking food while emitting light near the tail leg. When the end-of-life larva reaches the time of landing, it goes up the passage plate 28 provided in the aquarium 20 while emitting light in the vicinity of the tail foot in the water, reaches the soil 41, and crawls on the soil 41.

  When it hits an obstacle such as the side wall 11 of the transparent container 10, it remains as a safe place as a firefly habit, and then dives into the soil. At this time, since the light shielding plate 15 is provided, the light is diverted to a position in contact with the side wall 11 of the transparent container 10, and the light shielding plate 15 can be removed for observation.

  The instar larvae that have submerged in the soil 41 are moulted once and transformed into cocoons. Since fireflies emit light not only in adults, but also in larvae and pupae, it is possible to observe the mysterious light of the fireflies by removing the light shielding plate 15. Then, it becomes an adult over 20 to 50 days, rises from the soil 41 and jumps out into the air. At this point, the adult illuminates vigorously, so that the mysterious light can be enjoyed through the side wall 11 of the transparent container 10.

  When the firefly becomes an adult and starts to fly, the aquarium lid 25 is set in the opening 21 of the aquarium 20, and the water moss 45 is sufficiently contained and placed on the aquarium lid 25. The water tank 20 is appropriately supplemented with well water or purified tap water to create the firefly breeding / observation apparatus shown in FIG.

  The adult firefly drinks water with the planting 51 as a resting place. Adults mate immediately after they fly, and lay eggs in the moss 45 after mating. At this time, you can enjoy the light emission of the egg. The eggs grow up as first-instar larvae 30 to 40 days later, fall from the moss 45 into the water of the lower aquarium 20 through the plurality of through holes 26 provided in the aquarium lid 25, and start living in the water.

  As described above, according to the firefly breeding / observation apparatus according to the present embodiment, at the initial stage of breeding, the light emission of the last-instar larvae released into the water in the aquarium 20 can be observed from the upper part of the aquarium 20. . Next, after all the instar larvae have landed and dived in the soil 41, the light shielding plates 15 covering the portion of the soil 41 can be appropriately opened to observe the light emission of the moths. In the observation of wrinkles, the state of the whole wrinkles can be observed in an environment where the surroundings are bright, and the light emission of wrinkles can be observed in an environment where the surroundings are dark. Thus, the firefly breeding / observation apparatus according to the present embodiment can breed and observe the final instar larvae, pupae, adults, mating, egg laying, and birth of the first instar larvae.

  In the firefly breeding / observation apparatus according to the present embodiment, breeding after the first instar larva in the aquarium 20 is not planned. For this reason, in order to further raise 1st instar larvae, they are fed in a breeding facility where food is given and water management can be performed strictly. In addition, about the breeding / observation apparatus of the firefly after performing the breeding observation up to the first instar larva, it can be used for breeding / observation of the firefly through the same process as described above after obtaining the instar larvae again. . In this case, the soil 41 is preferably sterilized by sun-drying and added with well water or purified tap water so as to contain the original moisture. Moreover, about the transparent container 10, the water tank 20, and another member, it is suitable when it wash | cleans and uses.
