iNaturalist Observations: In and Around the Netherlands (30 May - 7 June 2026)

Green Immigrant Leaf Weevil
This trip to the Netherlands was quite productive from an observation standpoint. I was able to visit Leiden (great observations in the Hortus Botanicus), Delft (again, the visit to the TU Delft Hortus Botanicus was great), Amsterdam, Den Haag, and Scheveningen (mollusks!).

Total: 30 May - 7 June (as of 7 June 2026)

iNaturalist Highlight: 25,000th observation (Podisus maculiventris, the spined soldier bug)

Podisus maculiventris

On 21 May 2026, I uploaded my 25,000th iNaturalist observation, a nymph of the Podisus maculiventris, the spined soldier bug spotted in Hillside Park, Arlington, Virginia. 

As of this date, I've had 11 observations of the species (with some additional observations from the genus Podisus). A few days before this observation, I had another observation of a P. maculiventris attacking a much larger Nearctic Carpenter Ant (Camponotus nearcticus)

"Podisus maculiventris, the spined soldier bug, is a medium-sized predatory shield bug common in North America. It has prominent spines on each "shoulder" and preys on a wide variety of arthropods, particularly the larval forms of Lepidoptera and Coleoptera. As a generalist predator of many agricultural pests, P. maculiventris is generally considered a beneficial insect in gardens and crop fields." -- Wikipedia

Podisus maculiventris

P. maculiventris was first described by Thomas Say in 1831:

P. maculiventris, Hemelytra with a line at tip ; venter with five series of black points.

Inhab. U. S.

Body yellowish or pale brownish, with dense, rather large punctures : thorax acutely angulated each side behind the middle ; edge granulated before the middle : hemelytra having an abbreviated fuscous line at tip of the membranous portion : antennae, first joint short ; 2d longer than the third : tergum on the lateral margin with a blackish dot on each incisure : beneath yellowish : feet immaculate ; thighs sometimes having numerous minute blackish points ; anterior tibiae with an obvious spine over the slight emargination : venter with five obvious series of small black dots.

iNaturalist Highlight: 24,000th iNaturalist Observation: Atalantycha bilineata (Two-lined Leatherwing)

On 9 April 2026 I made my 24,000th iNaturalist observation (at left). The observation was of Atalantycha bilineata (Two-lined Leatherwing) spotted on a walk through Hillside Park (in Arlington, VA). I ended up observing three individuals (see all my observations of Atalantycha bilineata here).

Atalantycha bilineata was originally described by American entomologist Thomas Say in 1823 under the binomial name Cantharis bilineata in the Journal of the Academy of Natural Sciences of Philadelphia (volume 3, page 182):

6. C. bilineatus. Rufous; elytra black; thorax with two black lines. Inhabits the United States.

The eagle-eyed will note that Say indicates the species as C. bilineatus, not C. bilineata. Why you ask, well, the discrepancy arises from the gender of the species name, which must agree with the genus name Cantharis (feminine). While it was sometimes historically listed with the masculine suffix -us, the correct scientific name based on ICZN rules is Cantharis bilineata.

At right: Say, T. (1823). Cantharis bilineata. In Journal of the Academy of Natural Sciences of Philadelphia (Vol. 3, p. 182). Zenodo. https://doi.org/10.5281/zenodo.19498272

The species had kept the Cantharis bilineata name until 2005 when Sergey Kazantsev's review of the genus established the new Nearctic genus Atalantycha to accommodate certain species, including A. bilineata as a new combination.

iNaturalist Observations: In and Around Copenhagen (22-31 March 2026)

Nesting Mute Swan
I attended the 2026 GBIF Midterm meetings in Copenhagen in March 2026. I added on a few days of holiday to visit some of my favorites in the city.

The weather wasn't really good for a lot of observations and I didn't get out of the city, so many of my observations were of birds (especially around the Lakes). 

Total: 23-31 March 2026 (as of 1 April 2026)

First Spotted Lanternfly (Lycorma delicatula) observation of the year

 

Last year, I made my first Lycorma delicatula observation on 13 April 2025. This year, it was 10 days earlier (3 April 2025) in nearly the same spot. With the large number of (visible) egg masses in my neighborhood, I fear it will be another booming year. 

In 2025, I made 1,519 observations in Arlington, Virginia.

iNaturalist Observations: In and Around Croatia & Slovenia (14-25 February 2026)

 Croatia & Slovenia

February wasn't the best time of year to be doing iNaturalist observing in Croatia and Slovenia, especially in mostly urban locations. Lots of birds (and lots of Feral Pigeons). Plenty of opportunities for urban botanizing and, especially in Ljubljana, water fowl.

Croatia

At right is a Hooded Crow (Corvus cornix)

The hooded crow (Corvus cornix), also colloquially called just hoodie, is a Eurasian bird species in the genus Corvus. Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder. -- iNaturalist

At right is a European Firebug (Pyrrhocoris apterus): 

The firebug, Pyrrhocoris apterus, is a common insect of the family Pyrrhocoridae. Easily recognizable due to its striking red and black coloration, it may be confused with the similarly coloured though unrelated Corizus hyoscyami (cinnamon bug or squash bug). Pyrrhocoris apterus is distributed throughout the Palaearctic from the Atlantic coast of Europe to northwest China. Beyond its native Palaearctic range, it has been recorded in the United States, Central America, India, and Australia. It has been reported as recently expanding its distribution northwards into mainland United Kingdom and eastward on to the coast of the Mediterranean Sea.They are frequently observed to form aggregations, especially as immature forms, containing from tens to perhaps a hundred individuals. - iNaturalist
