Inktober #5 – binoculars
Today’s #inktober word is #binoculars. Well, that was easy one 🙂
Binocular microscope is very useful tool when you want to identify bees. Many bee species are, unfortunately, hard or impossible to identify to species without looking at them in magnification. That’s one of the reasons why entomological work involves much catching and killing. However, field identification of bees is increasingly more popular (thanks to, among others, many wildlife photographers and citizen scientists), and I believe it will be more and more developed, as new diagnostic traits visible in live specimens will be sought, allowing to identify more species without killing or even catching. Fingers crossed 🙂

Inktober #4 – exotic
#inktober, #beetober or #inktobee day 4: exotic
Exotic species are those which are not native for a given area but were introduced (puorposefully or accidentally) by humans. In Europe, we have at least one such species: Megachile sculpturalis, which was once a guest on this fanpage. Today I chose the European wool carder bee (Anthidium manicatum) which is not exotic for me – in Poland it is common native species – but was introduced to North America and is considered invasive alien species there.

Inktober #3 – boots
This bee is mostly described as having trousers not boots on her legs but I decided that’s close enough
Genus Dasypoda – Pantaloon bee in English, Hosenbiene in German, obrostka in Polish, all these names (including scientific one) refer to extremely hairy hindlegs of females. And how is this genus called in your language?PS I invented another # for #beetober: #inktobee

Inktober #2 – discover
Each year new bee species are described. There are also discoveries of new species for a country or region. On the cartoon you can see the ivy bee (Colletes hederae), whom you might remember from my older blog posts. This species is currently expanding its range in Europe, and discovered in the areas where it has never been seen previously. But there is also a quite interesting story of its discovery as a new species. It was described as late as 1993, even though it is a species living not in remote tropical areas, but in well-studied areas of Europe. It simply was thought to be a strange, late-flying individuals of other Colletes species, with a soft spot for ivy. Thanks to Schmidt and Westrich it was raised to the range of species.

Inktober #1 – backpack
I decided to take part in #inkober2024 and to make it a #beetober on my blog. The first drawing is a bit cheated, as I’m in a train and have only a gel pen with me, so it’s not exactly ink drawing.
Topic of day 1 is: backpack. What can it have in common with bees? Some do carry tiny backpacks, thanks to the curious scientists who want to know where they are going! Larger species, like honeybee or bumblebees, can be equipped with little transponders which allow to track their movements with the radar. Scientists can follow each individual bee and see where and when it forages. Crazy, isn’t it? 🙂f you want to see how bee backpacks look in real life, check this link: https://www.researchgate.net/publication/237085202_Unravelling_the_mechanisms_of_trapline_foraging_in_bees

Cellophane bee
Bees belonging to the genus Colletes are solitary, usually nest in the ground and line their nests with a cellophane-like substance which is an evolutionary achievement of their family, Colletidae. This family was once considered the most “primitive” of bee families but genetic analyses showed quite the contrary – they should be placed on the top of bees’ phylogenetic tree.
And here you can see a portrait of Colletes fodiens. It specializes in collecting pollen from plants belonging to Asteraceae family.

Skrócinka białonoga, mamrzyk skrócinkowiec
As I told you, I’m preparing portraits of Polish bees, and here is another one which I’d like to show you. Epeoloides coecutiens and Macropis europaea are both cute, and their parasitic relationship is interesting (like every relationship between a cuckoo bee and its host!). Did you know that Epeoloides coecutiens was once told to be the rarest species of bee in Europe? It is not the rarest, in fact, but in general cuckoo bees tend to be quite uncommon because of their lifestyle.
And fun fact: the Polish names of these bees are real tongue-twisters: skrócinka białonoga and mamrzyk skrócinkowiec
I just checked that if you paste these names into Google Translate, it can read it properly. So if you are courious how to pronounce these names, you can check there

The variable bumblebe
I’ve just began drawing a series of little portraits of bee species living in Poland. The drawings are referring to distinctive features of the species or their Polish names (or both
). Meet the pretty Bombus humilis, “trzmiel zmienny” in Polish, which translates into “the variable bumblebee and refers to extreme colour variability of this species.By the way, have you known that “nacked” bumblebees (ie, under their fur) are glossy black?

Listening
I did such a drawing of a bee (which was meant to be male Hoplitis cristatula, with his lovely bright blue eyes), and when I put it on my Facebook page, a friend of mine asked me if bees can hear.
Yes, they can! But not too well. They can receive frequencies between 20 and 500 Hz, so far narrower range than humans. Their hearing organs are located on their antennae, at the base of flagellum. These informations apply to honeybees, I don’t know about other bees being studied in this respect but I suppose it is pretty much the same between species.
