Abstract. Daily abundance at the breeding site and reproductive behavior of Polythore gigantea (Selys, 1853) are described in different localities of Antioquia, Colombia. Observations were done between March and June 2009 from 08:00 to 16:00 h. The highest reproductive activ- ity (i.e. maximal abundance of individuals at the breeding site) was observed between 11:06 and 12:12 h. Oviposition lasted 10 min on average. During courtship, the male exhibited rhythmical movements by opening and closing the wings rapidly, getting closer to the female and holding her in tandem. During oviposition, the female inserts the eggs inside wet trunks and little twigs in the surrounding vegetation under the close surveillance of the male. Males exhibit territorial behavior and conspecific aggression to defend the territory. Factors such as vegetation cover, might influence the time of the day in which oviposition occurs. This study provides, for the first time, information on the reproductive behavior ofP. gigantea . Key words. Dragonfly, damselfly, Zygoptera, Colombia, Antioquia

Abstract. Underwater oviposition is a special subtype of endophytic oviposition and con- stitutes the predominant mode for certain species of Calopterygidae and Coenagrionidae. Very little is known about underwater oviposition in Lestidae and other dragonfly groups (e.g., Anisoptera). In July 2009, we recorded this specific behaviour in a population of Lestes sponsa in the Czech Republic (Moravia, Štramberk). We subsequently studied the frequency of this phenomenon at regional (16 sites surveyed in an area of ca 1,260 km2) and local (proportions of eggs laid beneath and above the water’s surface at three locations) levels. We examined further key environmental factors influencing underwater oviposition and cer- tain ecological parameters (depth and time) of this behaviour in L. sponsa. The frequency of underwater oviposition on the regional scale was relatively low (< 20 %), but the frequency of this behaviour on a local scale was sometimes high. At those sites where underwater ovi- position occurred, 4,759 (62 %) out of a total of 7,699 eggs were laid underwater. The main factors affecting underwater oviposition were transparency of the water column and type of submerged vegetation. Ovipositing pairs spent on average 338 seconds under the water at an average depth of 20 cm. Further research should focus on the benefits of this specific oviposi- tion tactic and especially egg mortality during overwintering. Key words.

Abstract. We compared gregarine parasitism in imagines of Calopteryx splendens (Harris, 1780) and C. virgo (Linnaeus, 1758) collected at two sites with sympatric populations in the Spała Landscape Park, Łódź Province, Poland, in July 2012. Gregarine prevalence, intensity, wing load, and aggregation were compared between host species, sexes and sites. Among 140 individuals of both species collected from both sites, 81 (57.8 %) hosted gregarines. The distribution of the parasites was aggregated (k = 1.0064) and the highest intensity reached 40 parasites in a single host. There was no difference in gregarine prevalence between species. However, prevalence was different between sexes in both species. Females of C. splendens were more often parasitised at site 1, whereas in C. virgo males the prevalence was signifi- cantly higher at site 2. Secondly, the intensity of parasite infestation and aggregation rate was higher in C. splendens at both sampling sites, but we found no differences between sexes except at site 2 where males of C. splendens exhibited higher intensity. Thirdly, we found that the parasitism did not affect the damselflies’ wing load. Our study revealed differences in patterns of gregarine infection between species, sexes and sampling sites, which confirm that this system of parasitism is complex and influenced by many factors such as physiology and behavior of the host, environmental conditions or availability of gregarine infectious stages.

Abstract. During copulation, Ischnura asiatica (Brauer, 1865) males remove the sperm of the females’ previous mates from the spermatheca by stimulating vaginal sensilla thereby induc- ing sperm ejection. Because a wider penis head stimulates the vaginal sensilla more intensely, larger males with wider penis heads can remove much more sperm from the spermatheca. There are two distinct body sizes for spring (large) and summer (small) generations ofI. asia tica. In the present study we show that in spring, males have wider penis heads and females have a higher number of vaginal sensilla as compared to summer adults, suggesting that mat- ing males remove more spermathecal sperm in spring than in summer. However, interrupted copulation experiments showed that females of the spring generation had a higher number of spermatozoa in both sperm storage organs than those of the summer generation. Solitary females of the spring generation also had higher numbers of spermatozoa stored than those of the summer generation, suggesting that spring females might have larger sperm storage organs than summer females. Although the removal rate of bursal sperm was almost the same between generations, the removal rate of spermathecal sperm in the summer genera- tion was slightly higher than that in the spring generation. Consequently, spermatozoa de- rived from previously mated males have a higher probability of remaining in the sperm stor- age organs in spring- than in summer-generation females. The size of sperm storage organs in females might be critical to understanding sperm displacement. This aspect of female anatomy has not been previously considered in studies of sperm competition in odonates. Key words.

Abstract. Ischnura senegalensis (Rambur, 1842) has two female color-types: gynochromes, which are brown, and androchromes, which are green and similar in appearance to conspe- cific males.Ischnura senegalensis females from Okinawa Island, a small island in the Ryukyu Archipelago, Japan, show color-type frequencies that vary greatly, even among adjacent local populations. For example, androchrome frequencies were very low (0–4.3 %) in northern populations of the island. However, in the southern populations androchrome frequencies were high and ranged widely (0–67.2 %). Periodical surveys from 2011 to 2013 of two adja- cent southern populations revealed that the frequency of color-type remained constant over time. To our knowledge, this is the first study of temporally stable and extremely high inter- population variation in female color-type frequency in Odonata. We discuss possible reasons for the evolution of such high interpopulation variation in color-type frequency. Key words.

Abstract. To investigate if experimental marking affects the probability of resighting, 1,610 individuals of Mesamphiagrion laterale (Selys, 1876) and 630 individuals of Erythrodiplax umbrata (Linnaeus, 1758) were marked at two sites in Colombia and analysed with respect to marking variables as follows: marking colour used, which wing was marked, and a com- bination, i.e. the interaction, of these two. The colour and the marked wing were varied, using a different wing each time, and red, black, blue, or green colour. The information was analyzed using contingency tables (Chi-square test) to compare the probability of resighting for individuals within a population marked with a specific colour or on a specific wing to the probability of resighting for all other individuals in the population. In E. umbrata the resight- ing probability ranged as follows: 90.1 to 95.7 % (marking colour type), 90.4 to 95.2 % (wing used), and 87.5 to 97.8 % (wing-colour combination). In the case of M. laterale, the resight- ing probability ranged as follows: 57.2 to 65.0 % (marking colour type), 58.8 to 65.6 % (wing used), and 51.0 to 82.0 % (wing-colour combination). The colour, wing, or combination of wing-colour used for marking didn’t have an effect on the resighting probability, suggesting that the method and its variations are adequate to be used in mark–release–recapture studies on odonates. Recommendations are given on what has to be avoided to eliminate potential effects during the marking procedure. Key words. Damselfly, dragonfly, Zygoptera, Anisoptera, South America, Colombia
