Do you know how #fireflies woo their partners? They dine by candlelight but also with a good perfume! With @jakubecp, we have proven that #pheromones still play a key role in the bioluminescent #courtship of a night firefly. doi.org/10.1093/zoolin… #lampyridae #bioluminescence

Praha je plná světlušek💡🪲 Projekt Praha hledá světlušky pod vedením Martina Nováka z týmu Systematické a forenzní entomologie @fzpczu má za sebou již dvě sezóny a přinesl cenné informace o rozšíření svítících broučků na území hlavního města: 1url.cz/Su0fx

If you have a sample ready for fluid preservation, here's some advice on how to do it properly. And that alcohol doesn't have to be the only option. 🐞👉🧪

Made a key for carrion beetle larvae and their instars in the Czech Republic 💀🇨🇿researchgate.net/publication/37…

This is a little side project I've been working on with a couple of friends during the long and boring covid evenings. If you like relaxing puzzle games, check it out! Available on Android and iOS (PC soon). Fireflies included! Please follow us for more updates and content👾🫶👾

Presenting how to preserve your larval specimens to use them (not only) as criminal evidence later. In a beautiful city of @Liverpool attending #EAB2021.

Sometimes in life you just need to pick up that McD's spoon and fish out your Silphids. With @jakubecp

Our favourite after-lunch activity; checking necro-traps :-)

Just found out that our Thanatophilus sinuatus article is now available as pre-print here: link.springer.com/article/10.100…

It will be available to download in time 😉

@KwakWack Yes, in most species the adults are just sex machines, to use Lynn Faust's lovely expression. The glowing in larvae is considered to be mainly for the purpose of aposematic defence.

@FireflyerMartin Oh interesting, so I guess the adults only live to reproduce? Why would the larvae light up at night?

Wellcome to my firefly hotel where all your needs are met, breakfast included :-) #fireflies #lampyridae #fireflyhotel

After years of hard work, our interactive Key to forensically important beetle species of the Czech Republic is finally out! #forensicentomology #silphidae #staphylinidae #cleridae #nitidulidae #histeridae #geotrupidae #dermestidae #trogidae #leiodidae #interactivekey

@KwakWack These are firefly larvae and they are predatory. Adults of most species do not feed anymore. The most common prey are snails and earthowrms.

@FireflyerMartin I have two questions : What do fireflies eat? These don't fly, do they?

@jakubecp Who finds the sperm whale, gets 100 points 🐳

In case you were wondering, as me, how the #peniscollection looks like. At least small part of it. Here it is in all its magnificence. Thank you @FireflyerMartin and Jarin Qubaiova for preparing such a wonderful images. #beetlemorphology, #Coleoptera

This is a part of our Lab's gallery of carrion feeding beetles penises. FYI we take images of other body parts too... 😀

Taking ventral images of beetles is very important, as one can spot many interesting, and sometimes crucial traits. Here is an example of a ventral side of Catops joffrei (Coleoptera: Leiodidae).

New article is out! This time not directly about beetles, but about making great images of them 📸🐞 (even in low budget environment 😉). zookeys.pensoft.net/articles.php?i…

Although this looks like a Sperm Whale its actually only a penis of Philonthus spinipes Sharp, 1874. No pun inteded. #Staphylinidae, #macrophotography, @FesCuls
