ヤママユガの配偶行動と産卵の様子を30°C-24°Cの室温条件下において観察した。雌は羽化当夜からコーリング行動をとった。コーリングの時刻は日の入りから日の出に及んだ。本種のコーリングは,ポリフェムス蚕の場合と異なり,寄主植物葉なしの条件下でも活発にみとめられた。興奮した雄は腹側から雌の腹部に掴みかかり,交尾を行った。雌は羽化後3日間を通して高い交尾活性を示したが,雄の交尾活性は羽化後1日目のみに高かった。羽化当夜に交尾した雌では産卵活性の高まりに2日間を要したが,1日目またはそれ以後に交尾した雌では産卵活性の高まりはその後の1日間で十分であった。このことから,産卵活性の高まりには交尾のみならず,雌の日齢に連関した何らかの内的要因も関与していることが示唆された。

本研究では,まず野外および温室においてアオスジアゲハの配偶行動を観察し,次に雄の配偶行動を解発する視覚刺激をさまざまな標本及び色紙モデルの提示により調べた.本種の雄はパトロール型の配偶戦略を示し,積極的に飛び回って雌を探す.雌を発見すると,雌に接近し求愛を行った.交尾が成立する場合には,雌を見つけた雄は,しばらく追飛し雌がホバリングし始めるとその周りを縦に円を描くように垂直方向に飛び,雌が翅を閉じて止まるとすぐに交尾に至った.一方交尾が不成立に終わる場合には,求愛する雄に対して雌は翅を拡げた姿勢を示し,しばしば翅をはばたかせて雄を拒否した.次に,標本モデルの提示実験により,雄は交尾試行は雌モデルに対してより頻繁に行なわれたが,接近行動は雌,雄のモデルに対して同等に行なわれた.雄の接近は翅の黄色や黒いモデルよりも青い翅モデルにより頻繁にみられた.このことは色紙モデル提示実験において明らかとなった.すなわち,青色および緑色,特に濃い青色が雄の接近には有効であり,赤,黄および黒色は効果を示さなかった.また色彩パターン,サイズおよび形は雄の接近を誘起するには重要でなかった.これらの結果は,アオスジアゲハ雄の求愛行動を誘起するには翅の青色自体が有効であり,形や大きさ,それに色彩パターンは調べた範囲では関係なかった.従って,翅の青色化を誘導する羽化後の光照射は配偶行動に重要な意味を持っていることが推察される.

Brown and yellow types in the forewing fringe color in the so-called "Eurema hecabe (L.)" show sympatric distribution on Okinawajima Island in the Ryukyu Islands and occurrence of their characters is closely linked with seasonal wing morph expression and host plant use (Kato, 2000a, b). Further, these sympatric types are sexually isolated at the level of behavior (Kobayashi et al., 2001). In the present study, distribution pattern of these two types was investigated in southwestern Japan (16 sites) and Taiwan (3 sites) and their taxonomic status was reevaluated. In Amami-Oshima, Kuroshima, Kumejima, Taketomijima, Iriomotejima and Yonagunijima Islands, only the brown type was found while in Kagoshima-shi, and Okinoerabujima, Yoronjima and Tokashikijima Islands, only the yellow type was seen. Sympatric distribution of the two types was found in Tokunoshima, Okinawajima, Miyakojima, Ishigakijima and Haterumajima Islands, and Taiwan. The fringe color type was linked with seasonal wing morph expression and host plant use in all populations, as shown in previous papers (Kato, 2000a, b). These results strongly suggest that the two types have differentiated at the species level. The examination of the lectotype of Papilio hecabe Linnaeus, 1758 revealed that it was the brown type. Based on these, we here propose that the yellow type butterflies belong to a different species, Eurema sp.

A nymphalid butterfly Hestina assimilis assimilis, which was recently discovered in Kanagawa prefecture in Japan, undergoes larval diapause and show a seasonal change in wing color pattern: summer and spring (white) morphs. In the present study, temperature and photoperiodic conditions responsible for the control of seasonal morph determination was investigated. First, when post-diapause larvae were reared under various temperatures (15℃, 20℃, 25℃ or 28℃) at a long photoperiod (16L-8D), most of the eclosed adults were of white morph (spring morph). Second, larvae were initially exposed to a short photoperiod (10L-14D), and then transferred to 16L-8D to avoid diapause occurrence. Resulting adults were white morph. Third, individuals were reared at various temperatures (15, 20 or 25℃) under a long photoperiod (16L-8D) through larval and pupal stages. Low temperatures of 15℃ were quite effective for white morph production, but moderate (20℃) or high (25℃) temperatures were not effective, and all butterflies produced developed black veins on the wing (summer morph). Fourth, in experiments where different rearing temperatures were combined during the larval life, a temperature of 15℃ combined with 20℃, but not with 25℃, was effective for producing some intermediate or white morphs. Fifth, the temperature-sensitive stage for white morph production was mostly located in the 3rd and 4th instars (in partiular, 4th instar). In these experiments, white morph production was closely linked with extremely delayed larval development. The results strongly suggest that not only a short photoperiod, but also a relatively cool temperature including 15℃ is quite effective for white morph production even without an intervening larval diapause. Probably, an unknown neuro-endocrine mechanism may be responsible for the seasonal morph regulation as in the case of other butterfly species.
