A new invasive species: the American bug.

I noticed for some time the arrival of a new creature in the landscape:the american pushpin ou pine bug or even Leptoglossus occidentalis if you prefer.

An article dedicated to him in Le Parisien:

Beaujolais invaded by American bedbugs
This flying insect, which can measure up to two centimeters, is however harmless to humans.


Autumn takes with it its procession of rare insects. After the "diabolical bugs", observed in Paris, in the suburbs and in several departments, American bugs were detected on the Beaujolais side according to Le Progrès.

This insect from North America, which can measure up to two centimeters and is brown-red in color, has been seen by many inhabitants of Loire and Saône-et-Loire. "There are everywhere, in Cercié, Lantignié, Régnié-Durette ... We have a lot," testified one of them.
They attack conifers

Detected in France for the first time in 2005 - it was in Corsica - the so-called "pine" pushpin is perfectly harmless for humans and animals: it does not bite and does not spread disease, unlike the ferocious bedbugs of bed. From September to November, these bedbugs with long legs and antennae are looking for shelter to pass through the winter and sometimes rush en masse into homes.

However, the so-called Leptoglossus occidentalis can have a negative impact on its natural environment, especially on conifers. "It feeds on the seeds in the cones, by pricking them from its rostrum to suck out the lipid and protein reserves", explained in 2009 a review by the National Institute for Agronomic Research (INRA).

Warning, however, to those who would like to get rid of it. It is quite possible to eject them by hand or via a vacuum cleaner. Only, warns INRA, "just like for many other bedbugs, its sudden disturbance causes the emission of a foul odor ...".


Harmless for humans but whose impact is negative on conifers, which probably explains its presence in Beaujolais where spruce and Douglas-fir are very numerous.

The list of invasive species is starting to seriously increase, tiger mosquito (which should not cross the border!), Asian hornet, worms, Florida turtle, Seaweed Caulerpa Taxifolia and so on!

Do you have them at home?

Gardeners have a "chance" of soon knowing the misdeeds of the evil bug
The diabolic bug is native to Asia, where it is considered a major pest of fruit and vegetable crops. It was probably introduced in the USA before 1998, then in Switzerland in 2007. In the USA it colonized vast territories in the East before joining the West. For several years it has caused significant damage to a very large number of crops, in particular to fruit but also to soybeans, it is a very polyphagous species. It is also known to invade homes in very large quantities, in autumn, when it seeks shelter to winter. In Europe it has remained discreet for a few years but since 2012 it seems to be expanding its range. It is not yet causing damage in Europe, but a pest risk analysis (ANSES, 2014) concluded that it was an insect that potentially could inflict heavy losses on many of the most important agricultural productions for France (arboriculture, viticulture, market gardening etc.). The risk to human health and pets is limited, although cases of allergies have been reported in the USA. However, the inconvenience caused by thousands of bedbugs in homes in the fall will be significant.


Halyomorpha halys was discovered in France in summer 2012, in Alsace, but only reported in 2013 because of confusion with Rhaphigaster nebulosa (Poda, 1761), a fairly similar European bug. It is likely that the invasion will continue in France and monitoring its progress is important, both to warn the populations of the course of action to take in the event of an infestation and so that the agricultural sectors can prepare for possible crop damage. http://ephytia.inra.fr/fr/C/20532/Agiir ... diabolique
