Harmonia axydiris ladybugs in the Netherlands: here.
This video is called Green Tiger Beetle.
They saw over 100 green tiger beetles. This species had been absent from the island for decades; and is present again since 2004.
The entomologists saw three Platyderus depressus beetles in ‘t Grietje. This species lives only on Texel, not anywhere else in the Netherlands.
Also found: five other beetle species, including Stomis pumicatis.

The new species belongs to the very rare beetle genus Oryctophileurus.
“Like the other species of the genus, the new species might be rare or has a cryptic way of life,” wrote Dr Robert Perger from the Colección Boliviana de Fauna and Dr Paschoal Grossi from the Universidade Federal do Paraná, co-authors of the paper published in the journal ZooKeys.
The beetle, named Oryctophileurus guerrai, measures about 2 cm long by 1 cm wide.
“The species is named after our friend and colleague, Fernando ‘Fideo’ Guerra, for his lifetime commitment to the investigation of the Bolivian fauna. His participation in the actual survey in the southern Bolivian Andes has led to the discovery and description of several previously unknown taxa, and he was also the first to collect an individual of Oryctophileurus guerrai.”
Oryctophileurus guerrai resembles known species O. armicollis, but can be distinguished “by the distance between the inner teeth on the dorsal pronotal protuberance, and in females by the inner teeth separated by only a small fissure.”
Two specimens (female and male) of Oryctophileurus guerrai were collected in the northwestern buffer zone of the Tariquía Flora and Fauna National Reserve, department of Tarija, Bolivia.
“Oryctophileurus guerrai is known only from the northwestern area of Tariquía National Reserve in the southern Bolivian Andes. The forest in this area is considered subandine subhumid, semi-deciduous, Tucuman-Bolivian forest with a mean annual temperature of 18.7 °C and an annual rainfall of 1334 mm,” the scientists wrote in the paper.

This video is called Extinct hyenas tribute.
Among the finds so far in the coprolites is an Alpine marmot piece of bone. And a burying beetle shield. Scientists are still investigating which beetle species in the Nicrophorus genus that was. Had the beetle, like the hyena, been attracted by a dead mammoth?
In the Dutch province Limburg, Portuguese workers are exploited.
Fortunately, there is also better southern Europe-related news from that province.
Translated from the Stichting Bargerveen in the Netherlands, Friday 4 October 2013:
Tiny blind beetle, new for the Netherlands
A new South European ground beetle species has been found in the Netherlands. It is only two millimeters. Eyes and wings are missing and the creature lives underground. In 2012, the first three specimens were caught in Bemelen (south Limburg). This year, it turned out that the beetles live in large parts of the Bemelerberg hills. The journal Entomologische Berichten reports so this week.
While sorting out ground level traps of the Verlengde Winkelberg hill in Bemelen in 2012 a very small (about two millimeters), yellow-brown, eyeless beetle was found. Research by beetle expert Ron Felix concluded this was a male Anillus caecus, a beetle species which had never been found before in the Netherlands.
In 2013 there was more research in the Bemelerberg hills about the local distribution of this beetle. In total, another five individuals were caught at different locations. This justifies the assumption that the species is actually present in a large part of the Bemelerberg hills. …
This southern European beetle is known from the southwest of France. Observations are from the northern slopes of the Pyrenees to central France. …
How these blind, wingless beetles have managed to reach the Netherlands is difficult to say. The most obvious cause may be that humans brought them, for example, with vines from southern France. However, the possibility of a natural population cannot be completely ruled out. This beetle species has a very cryptic, subterranean lifestyle about which almost nothing is known.
Recently, a beetle species, new for Flanders, was discovered as well.

Animal Olympics: Rhinoceros beetles are the strongest animals in the world. Here is the proof.
From Wildlife Extra:
The European rhinoceros beetle is Europe’s strongest beetle, lifting up to 850 times their own body weight and is not considered a pest species in other countries.
Is it a pet, an introduced species or a recent arrival in the UK?
September 2013. Wildlife enthusiasts have been thrilled to discover a rhinoceros beetle in Worcestershire, a giant insect usually only found in mainland Europe.
Budding entomologist, Angie Hill found the huge beetle in her organic garden in Martley, Worcestershire and sent a photograph to Buglife for identification. Experts there were amazed at the exciting discovery and confirmed that it is a European rhinoceros beetle (Oryctes nasicornis), the same species as Dim, the beetle in the Disney film ‘A Bug’s Life‘.
Matt Shardlow, Buglife CEO said “We couldn’t believe it when we saw the photo; this is the first time one has ever been found in the wild in Britain. These gentle giants can grow up to 6 cm long and while the stag beetle can be longer, the European rhinoceros beetle is a robust beastie; this animal is probably the heaviest beetle in Britain.”
Angie said “I am delighted that this beetle has turned up in my garden and would love to know how arrived in a small Worcestershire village?”
Buglife are now asking for members of the public to keep their eyes peeled in the Worcestershire area.
Matt said “We need to find out whether it’s an escaped pet, an accidental introduction, perhaps with wood chips, or whether they are actually breeding in the wild. Worcestershire is an area famous for the Noble chafer (Gnorimus nobilis), and other rare beetles associated with dead wood. The rhino beetle feeds in decaying wood so it is possible they are breeding in an ancient wood in the Teme valley.”
If you find a similar looking beetle please take a photograph and send it in to Buglife. For more information and to help with identification, please visit www.buglife.org.uk.

Bored to Death
When the invasion went public in 2002, aliens had been living quietly in Detroit for at least 10 years. They were found out when a group of forestry scientists investigated a curious die-off in ash trees. They collected a small green beetle that none of them could identify. Eventually, a beetle specialist in Slovakia pegged it as Agrilus planipennis, the emerald ash borer. It had never before been recorded outside its native range in easternmost Asia. By the end of the year it had killed an estimated 7 million ash trees in Michigan.
It’s now one of the most destructive forest pests ever seen in North America—comparable to diseases such as chestnut blight and Dutch elm disease. There are 16 ash species and an estimated 8 billion ash trees in North America, and all of them are susceptible. “It’s this entire group of common eastern forest trees that could potentially get wiped out,” said Walter Koenig, a senior researcher at the Cornell Lab. “There isn’t anything controlling this outbreak at the moment.”
The adults don’t look like much of a threat: pretty, half-inch-long beetles with glittering green backs. It’s the nondescript beige larvae that do the damage. Armies of them hatch from eggs laid on the bark and then spend a year or two chewing through the tree’s cambium. Sixty thousand can emerge from a single tree. They can kill an entire stand in five years. They hitch rides in nursery trees, cut logs, and firewood—one reason never to take firewood along with you on camping trips—and they’ve already reached as far as New Hampshire and West Virginia.
In what may seem like cold comfort, their spread has at least caused a boom in food and nest sites for birds. In a recent study, a team led by Koenig gauged this ripple effect by pulling data from Project FeederWatch, a Cornell Lab citizen-science study that collects winter observations of feeder birds across North America.
The researchers chose areas of high, low, and no infestation, and compared FeederWatch reports of Downy, Hairy, and Red-bellied woodpeckers and White-breasted Nuthatches. They tested whether these bird species moved toward the increased food source, dispersed away from it, or showed up in higher numbers to nest in dead trees after the outbreak had moved on.
Their results indicated that Red-bellied Woodpeckers and White-breasted Nuthatches were more numerous in outbreak areas. The outbreaks didn’t seem to draw in birds, but those already living in the area showed evidence of higher reproduction and survival, perhaps because they benefited from the increased food supplies.
Modest though the response was, woodpeckers and nuthatches may be the ash trees’ best hope. One study found that woodpeckers could eat an average of 44 percent of the borer larvae at a site. But another study noted that very few native or introduced insect predators or parasites prey on the emerald ash borer.
And the insects have numbers on their side. “Woodpeckers can’t quite eat enough to keep up with them,” Koenig said. “Even if woodpeckers are eating 40, 50 percent of their young, that’s still an awful lot of emerald ash borers that are getting out there.”
At some point, insect predators or birds could step up their attacks on emerald ash borers and rein them in—nature does abhor a vacuum, after all. But for now, the increase in woodpeckers is the slimmest of silver linings. The most compelling take-home lesson is the ability of citizen science to aid scientists in a pinch. Koenig has used publicly collected data to answer similar questions about gypsy moths and sudden oak death. It’s a potent reminder of the irreplaceable role of citizen scientists when the scales are large and the stakes are high.

A new fly species for Britain found in Epping Forest & Norfolk
Fascinating fly discovery
July 2013. A new fly species for Britain has been recorded at Field Studies Council‘s (FSC) Epping Forest field centre recently following an insect conservation course taking place there.
Course tutor Martin Harvey spotted a tiny fly from the ‘scuttle fly’ family. He identified it as Phalacrotophora delageae which isn’t currently on the British species list.
Martin explains: “As the fly appeared to be new to Britain I sent the specimen to Dr Henry Disney, a leading world authority on the family of this fly, Phoridae, who confirmed the identification. However, Dr Disney also traced a previous record of this species back to Tony Irwin of Norfolk Museums. Tony had found this same species in 2006, but never formally published it as new to the UK. Myself and Tony are now writing up the two records so it can be added to the British list.”
Dr Disney also has links with FSC having run another field centre FSC Malham Tarn in Yorkshire, and working as a research fellow for the organisation.
Larvae feed on ladybird pupae
This type of fly is particularly interesting as the larvae of the flies in genus Phalacrotophora are parasitoids of ladybird pupae. The fly larvae develop inside the pupae of ladybirds, killing the ladybird in the process. In other parts of the world Phalacrotophora delageae has been reared from the pupae of various ladybird species, including the 7-spot, 2-spot and 10-spot.
The specimen itself has now been added to the world collection of Phoridae held at the Cambridge University Museum of Zoology.
Environmental education charity FSC runs many natural history courses throughout the year at its network of field centres, all led by experts in their field such as Martin.
