The adult sex ratio of the praying mantid Iris aratoria L. becomes increasingly female-biased as the season progresses. This 3-yr field study examines 3 possible causes of this shift in sex ratio: differences between the sexes in the date of adult eclosion, movement to and from the census area, and adult lifespan. In the field, male and female eclosion dates did not differ significantly. Movement to and from the census area was low for females and males. For each year, the number of females… 
Population Structure, Movement Patterns, and Frequency of Multiple Matings in Tenodera sinensis (Mantodea: Mantidae)
Examination of ecological components that should affect opportunities for multiple mating in wild populations of the Chinese mantid shows that mantids were most commonly found within the top 20% of two flowering plants, goldenrod and mugwort, which should place them in prime locations for capturing flying pollinators.
Seasonal aspects of sexual cannibalism in the praying mantis (Mantis religiosa)
This study suggests that the date of the last moult plays an important role in the occurrence of sexual cannibalism in the sexually cannibalistic praying mantis.
Sex ratio of apollo butterfly Parnassius apollo (Lepidoptera: Papilionidae) - facts and artifacts
The sex ratio bias was more pronounced in the wild population than in captive individuals caught after releasing into wild, which suggests that difference in detectability between the sexes is not the only reason for males outnumbering females.
You Are What You Eat: Food Limitation Affects Reproductive Fitness in a Sexually Cannibalistic Praying Mantid
Evidence that males and females are under different selective pressures with respect to resource acquisition is provided and one of very few to show an effect of juvenile food quantity on adult reproductive fitness in a hemimetabolous insect is shown.
Demography of the Heike firefly Luciola lateralis (Coleoptera: Lampyridae), a representative species of Japan’s traditional agricultural landscape
It was found that capture probability generally decreased as the season advanced, probably because of seasonal changes in detectability and/or firefly behavior, and the daily survival rate of adults decreased over the season and may be related to a seasonal decline in adult body size.
Survival of dragonfly Libellula fulva males according to their mating status: a four year study
The dragonfly is one of the favoured experimental groups of behavioural ecology. They can be marked individually and can be easily tracked without considerable disturbing. The use of mark-recapture
Mate attraction by females in a sexually cannibalistic praying mantis
The results refute the hypothesis of deceptive signaling and show that mate attraction signals of female T. aridifolia sinensis are honest indicators of female mate availability and a lower risk of sexual cannibalism.
A Comparison of Longevity Between Sexes of Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae)
This experiment was designed to determine lifespan differences between the sexes of C. macellaria, and results obtained showed no significant difference between the lifespans of males and females when exposed to laboratory conditions.
Spatial and Temporal Demographic Variation Drives Within-Season Fluctuations in Sexual Selection
It is demonstrated that there is within-season variation in sex ratio and density at multiple spatial and temporal scales that led to changes in the competitive challenges that males encountered at different times of the season and was correlated with significant variation in selection gradients on male size and weight between sampling periods.
Male‐biased sex ratios in mature damselfly populations: real or artefact?
Monitoring two field and three semi‐natural populations of the damselfly Lestes sponsa found biased sex ratios in diploid insect populations to be real or an artefact caused by different behaviours and/or different catchability of the sexes.
