Adult Geitoneura klugii klugii (Guerin-Meneville) and G. acantha ocrea (Guest) were collected throughout the 1985-86 flight season. Females were dissected to determine mating state and ovarian development on each occasion. Fecundity and duration of egg development were measured. Most females mate when pre-reproductive. Females were predominantly monogamous, and few instances of multiple insemination were revealed by spermatophore counts. Both sexes are reproductively active soon after emergence and neither species experiences any major delay in ovarian development. Oviposition occurs over an extended period with most eggs deposited singly. Fecundity of the two species is similar: follicle counts gave estimates of 200-280, and females laid similar numbers of eggs, up to 399 (G. klugii) or 323 (G. acantha). Eggs of G. acantha hatched, at a range of temperatures, within 2-5 weeks. In contrast, eggs of G. klugii developed but did not hatch, and it is likely that this species has a pre-hatching diapause. We suggest that this major difference between the two closely related co-existing species may reflect adaptations to preferred larval food-plants.

Burned Site

The apparent importance of successional habitat to pollinating insects, specifically bees (Hymenoptera) and butterflies (Lepidoptera) was quantified in an alvar landscape in the Ottawa valley through a comparison of burned and unburned alvar woodland. The two adjacent habitats on the same successional gradient were sampled by sweeping with additional data from pitfall traps for bees and by direct observation with close focus binoculars and occasional verification through capture with a net for butterflies. The sampling was done during 11 visits in 2008 beginning 16 May and ending 13 September. Both bee and butterfly diversity were higher in the post-fire burned alvar woodland compared to the adjacent unburned woodland based on species richness, number of individuals and Brillouin’s Biodiversity Index which takes evenness and heterogeneity into account. No bees were captured in the unburned area, but 34 species and 201 individuals were captured in the burned site. The most abundant bee species was Augochlora aurata. Lepidoptera were represented in the burned site by 35 species and 408 individuals compared to 15 species and 21 individuals in the unburned woodland. The most common butterfly species in the burned woodland was Callophrys polios. The higher diversity of pollinators in the burned site was correlated with both higher vascular plant diversity and much higher cover and frequency values for insect-pollinated plants providing nectar and pollen including flowering shrubs such as Amelanchier alnifolia var. compacta, Arctostaphylos uva-ursi and Prunus virginiana. The burned site also provided more cover of larval food plants for butterflies and apparently more nesting sites for bees. We suggest that a decrease in fire frequency and in the availability of open successional habitats are contributing factors in the decline of pollinators, and that endangered ecosystems where fire has been a natural phenomenon may require fire or fire-simulated management to sustain their biodiversity.

This is the first complete field guide to all butterfly species on Australia’s mainland and its remote islands. Written by one of Australia's leading lepidopterists, it is stunningly illustrated with colour photographs of each of the 416 currently identified species. There is also a distribution map for each species on the Australian mainland. It covers the five major family groups: Hesperiidae, Paplionidae, Pieridae, Nymphalidae and Lycaenidae, as well as the family Riodinidae, which has but a single species in Australia. The introduction covers adult structure, classification, distribution and habitats, and life cycle and behaviour. This is followed by accounts of each of the 416 species, giving common name, scientific name, and other names (if any), as well as details of behaviour, habitat, status, and larval food plants. Accompanying each species is a distribution map, and photographs of the upperside and underside of both male and female specimens. The book also contains a checklist of all species, a list of entomological contacts, a glossary, a bibliography, an index of common names and an index of scientific names.

Forty-three species of the Tortricid genus Peronea are dealt with, comprising all the species known to occur in Canada at the present time and including practically all of the North American ones. Characters found in both the male and female genital organs have been used as a means of specific differentiation and there are eight sets of figures illustrating these organs. The range of variation in color and pattern of the individual species is briefly discussed and records of distribution and larval food-plants are given as far as present knowledge permits. Seven species new to science are described.

The influence of the brain hormone on retention of blood in the mid-gut of the mosquito Aedes aegypti (L.) III. The involvement of the ovaries and ecdysone

The Brain

Most female mosquitoes require a blood-meal in order to produce mature oöcytes. An egg development neurosecretory hormone (EDNH), which is produced in the medial neurosecretory cells (m. n. c.) of the brain and stored in the corpus cardiacum, is released into the haemolymph following the ingestion of blood and is essential for the promotion of ovarian development to maturity. It has been shown that a factor from the m. n. c., presumably EDNH, is necessary if the blood-meal is to be retained in the mid-gut until the oöcytes approach maturity. The present paper shows that retention is not a direct result of the action of EDNH, but is dependent on the ovaries and may well involve ecdysone. Removal of the ovaries before a blood-meal leads to early haem-defaecation, but delay can be restored by injection of ecdysterone. Sub-threshold feeders and mosquitoes decapitated immediately after the intake of blood, each of which would be expected to eliminate the blood-meal early, also show a delay in the onset of haem-defaecation when injected with ecdysterone. Further, both in ovariectomized insects and sub-threshold feeders the time of onset of haem-defaecation is associated with the dose of ecdysterone given.

Abstract The Euro-Siberian Scarce Fritillary Euphydryas maturna is considered a vulnerable species in the European Union and is listed in Annexes II and IV of the Habitats Directive. The butterfly shows a complex pattern of larval plant use throughout its range. In central Europe females oviposit on some trees and bushes, especially Fraxinus spp., on which hatched larvae spend their pre-diapause phase of development feeding gregariously in conspicuous webs. However, some herbal plants are also reported in the north and east. During a study performed in the Natura 2000 area “Dolina Biebrzy” (Biebrza Valley) in NE Poland we recorded populations showing a unique mixture of ecological characteristics. Both Fraxinus excelsior and Veronica longifolia were used as larval food plants before hibernation, and some local populations seemed to be completely dependent on the latter plant. Moreover, in the spring, at one site, we observed larvae feeding on Salix rosmarinifolia - the first host record for this plant species. The importance of our findings for conservation, as well as for the monitoring of the butterfly, is discussed.

Larval food plants (LFPs) of Sri Lankan butterflies have been well documented recently with the aid of studies done by numerous researchers.  In this paper, we present further records, 118 LFPs used by 83 butterflies and 145 plant-butterfly combinations.  LFPs of Lethe dynsate and Potanthus pseudomaesa pseudomaesa are reported for the first time in Sri Lanka.  Important observations, possible LFPs and LFP preferences of rare and threatened butterfly species, are discussed.  This information on plant-butterfly interactions will play an important role in conservation management of both plant and butterfly species.
