During an inventory of insect diversity on Anticosti Island in 1993, we caught unprecedented numbers of Neospondylis upiformis (Mannerheim), a longhorned beetle rarely observed in eastern North America. All specimens were caught using 12-funnel Lindgren traps baited with 95% ethanol and α-pinene. This longhorned beetle was captured again in 2007 on Anticosti with the same traps. Other than that, seven specimens of N. upiformis were caught elsewhere in Quebec between 1993 and 2015. Only 14 specimens were found in the 45 most important insect collections of the province, the most recent specimen dating back to 1964.
At least 90% of the captures came from old-growth balsam fir stands of the south-central part of the island. Seasonal flight activity ranged from early June to late July, but adult captures peaked in early July. Results suggest that Anticosti Island might be a hot spot for N. upiformis in eastern North America, particularly in its south-central part where old-growth balsam fir forests still exist.

During a general inventory of beetle diversity carried out in 1993 on Anticosti Island, Quebec, Canada, we caught unprecedented numbers of Neospondylis upiformis (Mannerheim) (Coleoptera: Cerambycidae, Spondylidinae), a species formerly included in the genus Spondylis Fabricius (
Spondylidinae is a subfamily of Cerambycidae in which adults have short antennae (
In this paper, we compiled data on N. upiformis from various inventories carried out as a part of the biodiversity research programme of the Laurentian Forestry Centre of the Canadian Forest Service over the last 25 years and also from labelled specimens found in 45 of the most important insect collections in Quebec. We provide data on adult seasonal flight activity and update the distribution map of N. upiformis, suggesting that Anticosti Island might be a hot spot for this species in eastern North America.
Data were obtained from two sources: first, from field sampling and second, by compiling data from insect collections and from the recent literature. First, 12-funnel Lindgren traps (

Available temperature data were incomplete on Anticosti Island except in 2007, our last year of sampling on the island. Thus, we used the 2007 daily temperature averages from Havre Saint-Pierre and Cap-des-Rosiers, respectively on the north and south shores of the St. Lawrence River, to determine whether these data could be used as surrogates to express day-degree accumulation on Anticosti Island. In May 2007, degree-day accumulation on Anticosti Island followed very closely that of Havre Saint-Pierre but an average of Havre Saint-Pierre and Cap-des-Rosiers was a better fit in June and July (Suppl. material
Finally, 45 insect collections, including the most important ones in Quebec, were visited by one of the authors (SL) to authenticate N. upiformis specimens and compile data on labels (location, collection date and collector).
Spondylis upiformis Mannerheim, 1843
Neospondylis upiformis (Mannerheim) (Coleoptera: Cerambycidae, Spondylidinae) is a species formerly included in the genus Spondylis (Sama 2005).
A total of 340 N. upiformis adults were captured in baited Lindgren traps between 1993 and 2015 in 10 projects accounting for a total sampling effort of 5518 trap-days in the province of Quebec. It is many more than the 14 specimens found in 45 insect collections throughout the province. However, 333 of the 340 N. upiformis were collected on Anticosti Island, a location that had never been sampled before, which represents nearly 98% of the specimens captured for less than 24% of the sampling effort in our projects (Table
The first beetles were caught at the beginning of the sampling period, between 9 and 17 June 1993 (Fig.
In 1998, only four specimens were captured in a total of six traps located in the Jupiter River area (Table
Seven specimens were collected in five locations between 1993 and 2001, all on the south shore of the St. Lawrence River and in the eastern part of the province (Fig.
Overall, 14 N. upiformis specimens were found amongst 45 insect collections (Table

The data presented in this paper confirm that N. upiformis is uncommon in eastern Canada and has a very local distribution, as observed by
No records of N. upiformis had been reported by naturalists since 1964, suggesting that the habitat of this longhorned beetle may have rarified in southern Quebec. We did not capture any N. upiformis on the north shore of the St. Lawrence River, while five of the 14 specimens found in the collections were from this area. In fact, we only caught seven specimens elsewhere in the province of Quebec with attractive traps and a huge sampling effort over 22 years. The south-central part of Anticosti Island, to which belong the Jupiter River and the Pointe Sud-Ouest areas, was particularly rich in N. upiformis with 300 specimens out of the 333 caught on the island. These areas are mostly covered by old-growth balsam fir forests that survived previous hemlock looper, Lambdina fiscellaria (Guenée) (Lepidoptera: Geometridae), outbreaks (
The presence of N. upiformis has been reported in old-growth balsam fir and white spruce forests in protected areas of Newfoundland (
Whether Anticosti Island is a suitable habitat for N. upiformis because of the abundance of old-growth balsam fir forests, the presence of large white spruces, the particular climatic conditions or for any other reason is still unknown. White spruce is an increasing resource on the island and it should not limit N. upiformis abundance in the future, but old-growth balsam fir forests are rapidly disappearing (
We captured N. upiformis efficiently with 12-funnel Lindgren traps baited with high release rate lures of 95% ethanol and α-pinene, the same baits used by
