List of non-native arthropods in North America.


Ever since the first European explorers arrived in the American continent, plants and animals have been arriving along with them. It is estimated that 2,273 species of insects and arachnids have set residence in this continent (as of 1993), according to the North American Non-Indigenous Arthropod Database of the USDA or NANIAD.
Some were brought intentionally, others arrived on their own. With the increase in traveling and international commerce, the numbers of introduced species probably keeps growing even faster than in earlier times. Some of them become invasive, wreaking havoc in local ecosystems, not just the ones that were introduced accidentally, but also some that were brought intentionally for a variety of reasons and later on managed to escape and spread beyond control. More insects have been introduced intentionally than otherwise, especially to serve as biological controls. It is estimated that over 1700 species have entered this way; most of them are parasitoids or predators of pests.
Among the earliest pests that arrived in colonial times probably were the bed bug Cimex lectularius, cockroaches and the mosquito Aedes aegypti. Probably the earliest insects that were brought intentionally were the domestic bee Apis mellifera and the silk worm Bombyx mori. The silk worm is of no concern to us because, after thousands of years of domestication, it has lost its ability to survive on its own, and it is not found in nature. The honey bee on the other hand is a very resourceful and adaptable creature that has escaped domestication repeatedly and set up housekeeping in tree holes, other natural cavities and even hollow walls, much to the delight of bears and other honey-eating animals. Nowadays it is probably established in most states and there is no way to tell the impact that populations of domestic bees have had on native bees and on native flowers.

In addition to the comprehensive list issued by NANIAD there are a few other resources on the internet that may be of interest here:
A report issued by USDA Forest Service in 1994 lists 368 immigrant plant-eating insects. See:Immigrant Phytophagous Insects: an Annotated List., (a joint project of: The Bugwood Network, USDA Forest Service and USDA APHIS PPQ, the University of Georgia – Warnell School of Forest Resources and College of Agricultural and Environmental Sciences – Dept. of Entomology) lists 152 species of invasive insects. See Invasive insects.
A report of the University of Florida Invasive Insects (Adventive Pests Insects) in Florida lists 150 species of insects and 35 species of arachnids considered invasive in that state. Note that some of them were introduced to Florida from some other states, not from abroad.
The same thing applies to Invasive Species Resource List provided by the University of Pennsylvania.
Cornell University has a list of some insects used as biocontrols. See Biocontrols. Many of them, but not all have been introduced from other countries.
Perhaps the most complete list of species intentionally introduced as biocontrols is ROBO – Releases of Beneficial Organisms in the United States and Territories. It also includes a list of “target” species, the hosts of prey of the beneficial ones; most of them are undesirable non-natives.
Invasive Species Compendium. Only species considered invasive listed here. It is still useful.

Here, at BugGuide we have approximately 80 species of introduced insects and spiders (as of September 2005) and the numbers keep growing. I think that a list of non-native insects and arachnids with links to the corresponding pages would be of great value. I hope that everybody helps adding species that I missed or new ones as they are added to the guide. I hope to get your help with taxonomic issues, such as the proper sorting of families within larger taxa.

This list includes only non-native species featured in BugGuide in which there is a high degree of certainty of having been introduced. Others have been omitted, but will be added if somebody confirms that they are not native. For each species there is a link to the pertinent page with additional information if available. Please, notice that for practical reasons, I have not attempted to lists species that have been introduced from one region to another within North America. These introductions are no less important but would be difficult to include them here.

Couldn't find any indication that it's established but apparently it's in CA?:

order Phasmida is listed twice
Also a couple of taxonomy changes: all the Scapteriscus mole crickets are now Neoscapteriscus, Tenodera aridifolia --> T. sinensis

2 roaches
Chorisoneura parishi (1)
Symploce morsei (2)

Euborellia arcanum
Described from greenhouses in Germany with plants/soil from Florida, now appears to be present in FL, SC, TX, LA. Origin unknown, maybe Neotropics (1)

Elipsocus pumilis

Lepidoptera: Oligia latruncula
Oligia latruncula. Family: Noctuidae.

Introduced into NYC from Eurasia (1)

New introduction to Florida, native to West Indies
Alcimosphenus licinus (Tetragnathidae)

introduced harvestman

Cystiphora sonchi

some psyllids, Aphalaridae
Lemon Gum Psyllid, Cryptoneossa triangula. From Australia, 1995

--- Ctenarytaina eucalypti - proposed common name change to 'Blue Gum Psyllid' (widely accepted, "Eucalyptus psyllid" is ambiguous)
--- Ctenarytaina spatulata - proposed common name change to 'Rose Gum Psyllid' (per Queiroz, Burckhardt, & Majer 2012)

Springtail: Fasciosminthurus quinquefasciatus
Apparently not native, but I ran out of patience trying to figure out whether it originally comes from Australia or Europe, or maybe a different continent.

Native to Europe
Frans says it is native to Europe.

Millipede: Rhinotus purpureus
Rhinotus purpureus(1)

just name changes
For spiders, family Sparassidae, Pseudosparianthis cubana has been moved to Decaphora cubana (the link on this non-native list is broken, it doesn't re-direct to the name change for some reason).

Also for spiders, family Salticidae, Freya ambigua is now Leptofreya ambigua (the link on this list properly re-directs, so it's only the name that could be changed).

Collembola, Entomobryomorpha
Seira brasiliana:

From the neotropics; first collected in FL in 1980.

an introduced katydid
Leptophyes punctatissima. It seems to have become established on at least two occasions.

an apparently introduced cicada species
See here. I don't know any more than what's on the comments on the images.

Collembola: Homidia spp. and Coecobrya tenebricosa
Both Homidia(1) species are introduced. Quoting a paper on cave species (

"Homidia socia Börner, 1909 — TX IN [= trogloxene introduced, not state list -jfc]
Locality: Spider Cave
This is an introduced species. Almost all species of Homidia are restricted to East Asia and Oceania; only two (H. socia and H. sauteri) are known from North America. The oldest record of H. socia in North America appears to be from 1970, from Georgia (K. Christiansen, Collembola records database). The historical collection of springtails at the Illinois Natural History Survey that goes back to the second half of the 1800s, does not include representatives of this species, despite it now being the most common form found in grasses growing along country roads in Champaign County. Homidia socia was first noticed in a cave in Johnson County, southern Illinois, in 1973 (Christiansen and Bellinger, 1980, 1998; K. Christiansen, Collembola records database) and in Champaign County by the senior author in 1988. The species is also known from caves in Harrison and Crawford counties, Indiana."

The paper also calls Coecobrya tenebricosa(2) introduced:

"This species was originally described from the Washington, D.C., area, but currently it is known to occur around the world in protected habitats such as greenhouses and caves (Chen and Christiansen, 1997). The genus Coecobrya is almost exclusively East Asian in distribution (Chen and Christiansen, 1997), and it is likely that C. tenebricosa represents an early introduction, during historic times, into North America."

Eubule spartocerana (Coreidae)

From South America.

Elm Seed Bug
Arocatus melanocephalus (Lygaeidae):

From Europe.
