37-454: The blue dasher ( Pachydiplax longipennis ) is an insect of the skimmer family. It is the only species in the genus Pachydiplax . It is widely distributed throughout North America and into the Bahamas. Although the species name longipennis means "long wings", their wings are not substantially longer than those of related species. Females do, however, have a short abdomen that makes

74-436: A computer vision model which has been trained on the large database of the observations on iNaturalist. Multiple species suggestions are typically provided with the suggestion that the software guesses to be most likely is at the top of the list. A broader taxon such as a genus or family is commonly provided if the model is unsure of the species. It is trained once or twice a year, and the threshold for species included in

111-510: A global audience in 2018, with 68 cities participating from 19 countries, with some cities using community science platforms other than iNaturalist to participate. In 4 days, over 17,000 people cataloged over 440,000 nature observations in urban regions around the world. In 2019, the CNC once again expanded, with 35,000 participants in 159 cities collecting 964,000 observations of over 31,000 species. Although fewer observations were documented during

148-497: A higher likelihood of emerging in the presence of their predator, as opposed to weaker larvae likely emerging in the absence of the predator. Cannibalism also poses a threat, and the stronger larvae emerge earlier when this threat is high. This species is at a low vulnerability in regard to conservation. However, P. longipennis and all other dragonflies are indicators of a healthy ecosystem. As wetlands and other various habitats for dragonflies decrease due to habitat destruction, so do

185-401: A moth or fly. Nymphs have a diet that includes other aquatic larvae, small fish, and tadpoles. These dragonflies are known to be voracious predators, consuming up to 10% of their body weight each day in food. The blue dasher hunts by keeping still and waiting for suitable prey to come within range. When it does, they dart from their position to catch it. The foraging behavior of this dragonfly

222-507: A plane lace bug, Corythucha ciliata. This was the first recorded observation of the invasive species in the United Kingdom in about 18 years, and the observation sparked a national monitoring campaign to determine the spread of the insect in the country. Other research has focused on the morphology or coloration of species observations. For example, a study in 2019 assessed the relationship between wing coloration and temperature in

259-518: A species of mantis first discovered with the aid of iNaturalist was named Inimia nat so that its abbreviated form, I. nat , would be a word play that pays homage to iNaturalist. The Columbian weasel , the rarest neotropical carnivore, was seen for the first time in the 21st century when an iNaturalist user uploaded snapshots of the weasel exploring a privy. Two teenagers in California used iNaturalist observations of unfamiliar scorpions as

296-684: A stream, river, or lake. This species has now been spotted in lower portions of Canada (Ottawa), and it is suggested that climate change is allowing for a broadening of this species’ distribution. Dispersal of this species is linked to territorial behavior. Males of this species exhibit extreme territorial behavior, often leading to repercussions for smaller males. Smaller males tend to be driven away from breeding grounds by larger males, resulting in these smaller males dispersing to other areas. Researchers believe that this method of dispersal could be important in further studies of population genetics and gene flow of this species. Wing coloration also varies with

333-415: Is open source . Scientists have published more than 4,000 papers drawn from iNaturalist data sets and observations, including descriptions of species new to science and rediscoveries of species so rarely seen they were feared extinct. iNaturalist began in 2008 as a UC Berkeley School of Information Master's final project of Nate Agrin, Jessica Kline, and Ken-ichi Ueda. Agrin and Ueda continued work on

370-585: Is influenced by different factors, such as external temperature, prey availability, and perch position. P. longipennis tends to forage on small prey, which differs from the unselective foraging behavior of other Odonata species. This species also moves to different foraging sites frequently, meaning they do not stay put in one place too long searching for food. P. longipennis also exhibits aggressive behavior when foraging for food. Both males and females take part in this aggression when looking for prey. P. longipennis will engage in this behavior towards individuals of

407-521: Is mostly New World , but also has one of the few endangered odonates from Japan: Libellula angelina . Many of the members of this genus are brightly colored or have banded wings. The related genus Plathemis includes the whitetails. The genus Celithemis contains several brightly marked species in the southern United States. Members of the genus Sympetrum are called darters (or meadowhawks in North America) and are found throughout most of

444-457: Is not a science project itself, iNaturalist is a platform for science and conservation efforts, providing valuable open data to research projects, land managers, other organizations, and the public. It is the primary application for crowd-sourced biodiversity data in places such as Mexico, southern Africa, and Australia, and the project has been called "a standard-bearer for natural history mobile applications." Most of iNaturalist's software

481-423: Is not a strict requirement. Users may share observation locations publicly, "obscure" them to display a less precise location or make the locations completely private. On iNaturalist, other users add identifications to each other's observations in order to confirm or improve the identification of the observation. Observations are classified as "Casual", "Needs ID" (needs identification), or "Research Grade" based on

518-478: Is still classified as a summer species. The larvae of this species often vary greatly in regard to size due to generational overlap of groups. This generational overlap is created by some groups producing one brood and other groups producing two broods in a breeding season. The timing of P. longipennis larvae emergence has also been linked to the presence of its predator, Anax junius . Research has shown that if larvae are in their peak physical state, then they have

555-591: The Libellulidae , the largest family of dragonflies . It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species. With nearly worldwide distribution, these are almost certainly the most often seen of all dragonflies. The genus Libellula

592-534: The National Geographic Society . Since 2012, the number of participants and observations has roughly doubled each year. In 2014, iNaturalist reached 1   million observations and as of October 2023 there were 181   million observations (163   million verifiable). On 11 July 2023, iNaturalist became registered as an independent 501(c)(3) nonprofit organization. Users can interact with iNaturalist in several ways: On

629-878: The Natural History Museum of Los Angeles County and Alison Young from the California Academy of Sciences co-founded the City Nature Challenge (CNC). In the first City Nature Challenge, naturalists in Los Angeles and the San Francisco Bay Area documented over 20,000 observations with the iNaturalist platform. In 2017, the CNC expanded to 16 cities across the United States and collected over 125,000 observations of wildlife in 5 days. The CNC expanded to

666-469: The 2020 City Nature Challenge during the COVID-19 pandemic (when the CNC became collaborative as opposed to competitive), more cities and people participated, and more species were found than in previous years. Users have the option to license their observations, photos, and audio recordings in several ways, including for the public domain , Creative Commons , or with all rights reserved . To encourage

703-804: The Global Amphibian and Global Reptile BioBlitzes, in which observations were used to help monitor the occurrence and distribution of the world's reptiles and amphibian species. The US National Park Service partnered with iNaturalist to record observations from the 2016 National Parks BioBlitz. That project exceeded 100,000 observations in August 2016. In 2017, the United Nations Environment Programme teamed up with iNaturalist to celebrate World Environment Day . . In 2022, Reef Ecologic teamed up with iNaturalist to celebrate World Oceans Day .

777-544: The description of new species or rediscovery of species previously considered extinct. For example, a species of snail, Myxostoma petiverianum , first described in the 1700s, was also rediscovered in Vietnam . Additionally, in 2013, a citizen scientist in Colombia uploaded a photo of a poison dart frog , which researchers determined was a previously unrecognized species now known as Andinobates cassidyhornae . In 2023,

814-595: The first step in their eventual description of two new species. The frosted phoenix moth of New Zealand, feared extinct, was "rediscovered" when a Swedish birder who was in town to see kiwis put up a light to attract moths and snapped a casual photo of an insect that had parked itself under a lawn chair on his hotel balcony; his upload to iNaturalist was the first time the moth had been seen alive in 65 years. A commuter in London uploaded an observation of an insect on her bag to iNaturalist, which allowed it to be identified as

851-576: The iNaturalist research-grade observations hosted on the Global Biodiversity Information Facility (GBIF), often in the fields of ecology, conservation, and climate change . Many articles focus on climate-driven range shifts and expansions. For example, in 2015, data from iNaturalist was used to show that the Hopkin's rose nudibranch ( Ceratodoris rosacea ) is moving northward. Other published research focuses on

The website provides tools for registered users to add, identify, and discuss observations, write journal posts, explore information about species, and create project pages to recruit participation in and coordinate work on their topics of interest. On the iNaturalist mobile app, registered users can create and share nature observations to

925-430: The male, along with contrasting red eyes. Both sexes develop a frosted color with age. Pachydiplax longipennis exhibits aggression while finding mates and foraging, and they are not under any conservation threats. Pachydiplax longipennis is a commonly spotted dragonfly species in the United States, and this species is found in many types of habitats. These habitats generally consist of some kind of body of water, like

962-432: The online dataset, explore observations both nearby and around the world, and learn about different species. Seek by iNaturalist, a separate app marketed to families, requires no online account registration and all observations may remain private. Seek incorporates features of gamification , such as providing a list of nearby organisms to find and encouraging the collection of badges and participation in challenges. Seek

999-613: The populations of dragonflies. Therefore, dragonflies are at the forefront of conservation movements. In regard to global warming, studies have shown that increasing temperature has an effect on larvae emergence time and survival. Larvae under the conditions predicted for 100 years in the future emerge significantly earlier, and their survival rate is much lower, indicating possible effects of global warming on this dragonfly.

1036-552: The quality of the data provided and the community identification process. Any quality of data can be downloaded from iNaturalist and "Research Grade" observations are often incorporated into other online databases such as the Global Biodiversity Information Facility and the Atlas of Living Australia . In addition to observations being identified by others in the community, iNaturalist includes an automated species identification tool, first released in 2017. Images can be identified via

1073-883: The range of this species, indicating that dispersal location and wing coloration are connected. Populations of P. longipennis occurring in more hot regions tend to lack the darker wing coloration present in populations in cooler regions. This darker wing coloration can help with thermoregulation, flight performance, and territory securement. Thus, temperature has a large effect on the evolution of this species’ wing coloration across its dispersal range. Blue dashers live near still, calm bodies of water, such as ponds, marshes, slow-moving waterways, and ditches, in warm areas typically at low elevations. The adults roost in trees at night. These dragonflies, like others of their infraorder, are carnivorous, and are capable of eating hundreds of insects every day, including mosquito and mayfly larvae. The adult dragonfly will eat nearly any flying insect, such as

1110-472: The same species and individuals of other species, but males tend to fight (and win) more often than females. Researchers suggest that the more successful an individual is using aggression, then the more likely they will gain a better perch and thus increase their chance to find prey. Pachydiplax longipennis larvae exhibit asynchronous emergence, meaning that the larvae do not emerge at the same time as one another. Based on general time of emergence, this species

Ueda and Loarie are the current co-directors of iNaturalist.org. The organization merged with the California Academy of Sciences on April 24, 2014. In 2017, iNaturalist became a joint initiative between the California Academy of Sciences and

1221-400: The species that occur within a designated area, and a specific project type on iNaturalist. Other project types include collections of observations by location or taxon or documenting specific types of observations such as animal tracks and signs, the spread of invasive species , roadkill , fishing catches, or discovering new species. In 2011, iNaturalist was used as a platform to power

1258-508: The training set has changed over time. It can be difficult for the model to guess correctly if the species in question is infrequently observed or hard to identify from images alone; or if the image submitted has poor lighting, is blurry, or contains multiple subjects. Users have created and contributed to tens of thousands of different projects on iNaturalist. The platform is commonly used to record observations during bioblitzes , which are biological surveying events that attempt to record all

1295-439: The wings appear longer in comparison. The blue dasher grows up to 25–43 millimetres (0.98–1.69 in) long. The males are easy to recognize with their vibrant blue color, yellow-striped thorax, and metallic green eyes. Females are somewhat less colorful than the male, an example of sexual dimorphism . While they have a matching yellow-striped thorax, their abdomen has a distinct brown and yellow striping that sets them apart from

1332-746: The world, except Australia. Several tropical species in the genera Trithemis and Zenithoptera are considered to be especially beautiful. Other common genera include Tramea and Pantala . The libellulids have stout-bodied larvae with the lower lip or labium developed into a mask over the lower part of the face. The family name may have been derived from the Latin libella which means "booklet". The Libelluidae contain these genera : INaturalist iNaturalist describes itself as "an online social network of people sharing biodiversity information to help each other learn about nature," with its primary goal being to connect people to nature. Although it

1369-596: Was initially released in the spring of 2018. The iNaturalist platform is based on crowdsourcing of observations and identifications. An iNaturalist observation records a person's encounter with an individual organism at a particular time and place. An iNaturalist observation may also record evidence of an organism, such as animal tracks , nests , or scat . The scope of iNaturalist excludes natural but inert subjects such as geologic or hydrologic features. Users typically upload photos as evidence of their findings, though audio recordings are also accepted, and such evidence
