Les Papillons de la République Dominicaine

Dans ce texte, Peter Hall raconte son expérience d’observation des papillons en République dominicaine pendant l’hiver nordique. Sans louer de voiture, il a exploré la péninsule de Samaná à pied depuis un petit hôtel à Las Galeras. Pendant sa semaine là-bas, il a identifié 48 espèces de papillons, dont des endémiques de l’île d’Hispaniola. Il met en évidence la présence d’espèces telles que Calisto et divers sphingidés. De plus, il mentionne l’observation d’espèces rares et endémiques, telles que l’Hesperiidae V-mark haïtienne et le papillon Dynamine. Il partage également des découvertes sur les distributions de certaines espèces et les sources littéraires consultées.

Le papillon le plus élevé d’Amérique du Nord enregistré.

Perché dans la zone alpine du mont Whitney, le plus haut sommet de Californie, se trouve une population de la sous-espèce du Chryxus Arctique connue sous le nom d’Arctique d’Ivallda (Oeneis chryxus ivallda). Grâce à Zachary MacDonald et à ses collègues qui l’ont trouvée, elle est également connue comme la plus haute papillon d’Amérique du Nord. L’équipe a récemment publié ses découvertes et elles sont désormais partagées avec e-Butterfly.

Papillons rares dans le nord de l’État de New York

Parmi les habitats les plus uniques et les plus menacés de l’est de l’Amérique du Nord se trouvent les plaines de sable du centre de l’État de New York. Les dunes localisées et vallonnées de cette région sont recouvertes de pins à crochets avec une végétation basse dominée par des lupins de soleil. Cette combinaison en fait également l’un des derniers bastions pour plusieurs espèces de papillons qui sont également menacées.

Après deux décennies de recherche, une rare papillon est découvert lors de l’Atlas des papillons du Vermont.

Presque chaque printemps au cours des 21 dernières années, Bryan Pfeiffer s’est aventuré dans certains des marécages les plus reculés du Vermont. En chemin, il a fait don de son sang aux mouches noires, s’est enfoncé dans la boue et s’est parfois demandé s’il sortirait vivant de certains marécages.

Dix trucs pour photographier les papillons (sans nouvel appareil photo)

(English) The butterflies are out and many of us are eager go butterflying with our cameras and bring images home to share. While I don’t fancy myself as an expert photographer, I sure love to photograph butterflies and other insects. I realized over time that many tricks I took for granted to approach butterflies were foreign to many naturalists especially those new to it. After sharing some tips on how to approach butterflies and better photograph them with friends and colleagues and seeing them come back with much improved results and more species than they use to find, I thought this might be helpful to share.

Les Vermontois sont invités à aider à la recherche de papillons

Les Vermontois ont maintenant une autre excuse pour sortir pendant les journées ensoleillés : se joindre à une enquête à l’échelle de l’État sur les insectes les plus charismatiques – les papillons. Le Vermont Center for Ecostudies (VCE) recrute des bénévoles pour aider à fouiller des champs et des marais, des montagnes et des prairies, et même leurs propres arrière-cours pour documenter l’état des papillons du Vermont.

Déclin des monarques observé dans les sites d’hivernage mexicains

La situation de la population de l’est du monarque migrateur  est préoccupante.

Ce “musée” en plein air est à la fois un zoo, un musée d’histoire naturelle et un jardin botanique mais, peu importe comment on l’appelle, l’ASDM est l’endroit tout indiqué pour découvrir la biodiversité du désert de Sonora, des mygales aux chèvres de montagne, en passant par les pécaris. Le jardin botanique met en valeur la végétation unique de la région.

Un papillon rare mangé par une grenouille menacée

Pendant deux semaines de vacances en Arizona à la fin du mois d’octobre, j’ai visité la réserve naturelle du canyon Ramsey, dans les montagnes Huachuca. Lors d’une randonnée le long du ruisseau dans le canyon, je suis tombé sur un petit étang couvert de lentilles d’eau. Une piéride de Chiricahua femelle (Neophasia terlootii), une espèce rare et très localisée, s’est posée sur la végétation flottant à la surface pour boire.

Hausse de la population de monarques de l’est

(English) The presence of monarch butterflies in Mexico’s forests this past winter was 35% greater than the previous year, according to the most recent survey led by WWF Mexico. This increase marks a sign of recovery—albeit a fragile one—and gives some reason for hope against a backdrop of several decades of decline for the iconic species. According to the survey, Forest Area Occupied by the Colonies of Monarch Butterflies in Mexico During the 2021-2022 Overwintering Season, the species’ presence in and around Mexico’s famed Monarch Butterfly Biosphere Reserve grew from 5.19 acres in December 2020 to 7.02 acres in December 2021.

Une jeune Inuk découvre une nouvelle sous-espèce de papillon dans le cadre d’un programme de l’Insectarium de Montréal

(English) It was a cloudless midsummer day in 2019 when Siaja Parceaud-May noticed a Booth’s sulphur butterfly that had some “noticeable differences.” She was about an hour north of her home community of Kuujjuaq in Quebec’s Nunavik region with a team of entomologists and researchers from the Montreal Insectarium, learning how to identify and collect butterflies. Along a sandy, cleared ridge toward Ungava Bay, she spotted the peculiar critter that would be sent to Montreal for further analysis. Her hunch turned out to be right. More than a year later, insectarium director Maxim Larrivée wrote to her — confirming that she had discovered a new subspecies of Colias tyche. To her surprise, it would be named in her honour: Colias tyche siaja.

(English) Recorded Webinar: Using Community Science Data to Monitor Butterflies

(English) Butterfly walks are not only a relaxing activity, but also an invaluable source of data for science. Join Dr. Federico Riva as he discusses the importance of the checklists recorded in eButterfly for his work: (i) the use of butterfly checklists to understand population changes and inform conservation practices; (ii) the importance of “imperfect detection” – our inability to see all butterflies when we are looking for them – and how we can maximize the number of butterflies that we see at a site; (iii) his current work with eButterfly, that leverages thousands of observations from community scientists to help understand regions of conservation priority across North America.

Un stagiaire post-doctoral se joint à l’équipe de eButterfly

Nous sommes heureux d’accueillir Federico Riva, PhD pour un stage post-doctoral. Au cours des prochains mois, il étudiera la répartition des papillons de jour d’Amérique du Nord et les tendances de leurs populations dans le but d’améliorer les méthodes de suivi. Nous lui avons demandé de nous parler de son parcours et de son expérience avec les papillons. Bienvenue dans l’équipe de eButterfly, Dr Riva!

Mise à jour de la taxonomie dans eButterfly

Climate Generalist Butterflies Expected to be Winners Under Climate Change in Canada

Forecasting species responses to climate change is integral to the development of adaptive and practical conservation decisions. Butterflies are climate-constrained in at least two ways, as ectotherms, the climate has a defining role in dictating where butterflies can live. Additionally, a warming climate may have huge impacts on their host plant availability. These constraints could mean certain butterfly species may have to move north, or up in elevation, to stay within their preferred temperature range. Predicting how butterflies might respond to such temperature and host plant shifts could inform decisions involving conservation prioritization, species management, and natural resource management.

(English) New eButterfly Updates Just in Time for Spring

(English) We’re excited to announce some great improvements and new tools for eButterfly that we just released, with even more on the way. Our team has worked hard all winter to improve how the communications center operates, adding additional languages, upgrading the checklist submission process, improving the user experience for viewing checklists, updates that increase the performance of eButterfly, and many minor bug fixes.

(English) A Giant Leap for a Butterfly in Vermont and Beyond

(English) In 2010 when the largest butterfly in North America fluttered among Ardys Fisher’s flowers at the end of July, she knew it was something neat. Now, our study published in Frontiers in Ecology and Evolution this week shows an unusually rapid northward range shift by the Eastern Giant Swallowtail over the last two decades.

(English) Dramatic Decline in Western Butterfly Populations Linked to Fall Warming

(English) Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.

(English) 2020 eButterfly Year in Review

(English) From the first observation of 2020, a Gulf Fritillary nectaring on the Gulf coast of Florida submitted by Gary Leavens, to a Long-tailed Skipper nectaring at the end of December shared by mbspang, butterfly watchers added over 38,500 butterfly records to the ever growing eButterfly database of checklists. The reports fluttered in all summer long. We had more than 8,300 checklists with over 22,000 photographs comprising 523 species of butterflies reported during the year.

(English) International Monarch Monitoring Blitz 2020

(English) From July 24 to August 2, 2020, volunteers in Canada, Mexico and the United States helped monarch experts gain more information to enable better understanding of the distribution of the migratory monarch butterfly, an emblematic North American species. This year 520 volunteers across 68 states and provinces participated in the Blitz. They recorded 9,649 monarchs at various stages of their life cycle, from eggs to full-fledged butterflies. And together, they monitored 40,321 milkweed plants, the sole food source for monarch caterpillars.

(English) Climate Change Could Cause Decline of some Alpine Butterfly Species

(English) The long-term effects of climate change suggests that the butterfly effect is at work on butterflies in the alpine regions of North America, according to a new study by University of Alberta scientists—and the predictions don’t bode well. The researchers used climate change models to understand the effects of changing ecosystems on alpine butterflies in North America. The results show that alpine butterflies who have specialized diets, meaning that they feed on one or a few plants, are more vulnerable to climate change because of fluctuations in their food. On the other hand, butterflies that have diverse diets are less likely to be affected.

(English) The Quest for My Biggest Butterfly Holy Grail – Jamaican Giant Swallowtail

(English) ‘Holy Grail’ butterflies are those rare, remote, hard-to-find, attractive species that linger in the imagination. For Peter Hall, the holiest of grails for many years, beginning in his childhood, was the Jamaican Giant Swallowtail (Papilio homerus). It was more like a myth than an actual species – seen by few and living in only two isolated and diminishing locations in the remoter rainforest of the Caribbean island, Jamaica.

The Waltz of the Hickory Hairstreaks

I have the great fortune of living in a mature hardwood forests on a two acre lot in Rigaud, Québec, Canada. This has allowed me to witness butterfly and moth behaviour and phenological events in ways I had never experienced in the past. This morning, similarly to last July, the first thing I saw when I […]

Admirals at Sea

Drifting in a boat several miles out in the Gulf of Maine, Chris Rimmer, director of the Vermont Center for Ecostudies, didn’t expect to see any butterflies. It was a warm July afternoon (well, for the coast of Maine) and Chris didn’t expect to see many birds either. But to his surprise, through his binoculars, […]

A Target on Your Back Is Useful

Life is hard, especially if you’re a butterfly. Always feels like there is a target on your back.

Having eyespots allows butterflies to live longer and lay more eggs. Surprisingly this deflection hypothesis […]

Sharing Your Historical Data with eButterfly

By Peter Hall, Ottawa, Ontario My butterfly watching began in childhood when I chased a Cabbage White around a schoolyard in Ajax, Ontario, and caught it in my cap. Almost sixty years later I’m still at it. In the early days, I did some collecting, but did not keep any field notes as there was nobody to […]

June eButterflyer of the Month: Roy Pilcher

Collecting birds’ eggs […]
