The report from Butterfly Conservation Trust on the recent population trends on Butterflys
For those who might be interested
How the heatwave and drought afected Butterflys this year
And then a new species of moth
And a database brings these together for the very first time
And then of course we can share any interesting facts about wildlife and wildlife populations with each other but it doesn’t have to be in the form of a link if you know any facts or even know any from something youv read or been told or learned or maybe even know from memory you can share them here too not so much news but interesting facts
Thats cooll. The post isn’t just facts about Butterflys though it’s any facts you know about any wildlife for example did you know that Invertrevretes that can see in ultraviolet can’t see red that is there blind spot whereas ultra violet is a humans blind spot but insects and invertrevretes that see in ultraviolet can see the purple and Blue Spectrum a lot better and Bumblebees can only see im ultraviolet so there’s some coloured flowers they see better than others but plants have something on them that tell them where the nectar is and that when a Bumblebee lands on a plant it can tell weather a Bumblebee has already been there and if it has already been pollinated or not
And did you know that Bats arnt actualy blind and also people usually associate bats with vampire bats but actually we don’t have any in this country.
And also did you know that grasshoppers and crickets have differant types of calls depending on the species and also not all grasshoppers or crickets necessarily have wings
And did you know that a Kestrels diet is mainly voles and did you also know that Kestrels are in Decline in Gloucestershire and that they can see in ultra violet so they can pick up on urine trails
Any did you facts any one knows. Links are ok and your welcome to send them but you don’t have to send them it’s mainly comment facts mostly iv got alot more facts fo share with everyone than iv already written that I know aswell in case anyone would like to hear anymore. And if anyone knows any did you know facts feell free to comment
If your asking if I can add the butterfly report links to your project I might remove the links from the post and add it to your butterfly project links.
And then after removing the links from the post il replace the links with did you know facts so that the post is more understandable
But if the link is just linking to a fact from your project to the Butterfly video about it that is ok. im just wondering weather your asking me to add the butterfly report to your project or weather your just linking to the project with the link about the report
Bumblebees (Bombus impatiens and Bombus terrestris, at the least, have been investigated) have green, blue and NUV (bee purple) photoreceptors. The green photoreceptor has a peak sensitivity in the green part of the spectrum, but detects light all the way from the near ultraviolet to the fringes of red (i.e. including orange and yellow). The NUV and blue photoreceptors have narrower peaks of sensitivity cutting out at about cyan and yellow respectively.
This combination of photoreceptors is widespread in Hymenoptera, but the same paper I took the above data from mentions a solitary bee (Callonychium petuniae) that has a 4th type of photoreceptor, which one might call red. (It might be shifted towards orange compared to the human receptor.) Bees are also sensitive to the polarisation of light
Mammals generally have poor colour vision, which is believed to be due to their ancestors have passed through a nocturnal stage, reducing in loss of photoreceptor genes in the absence of stabilising selection. Most mammals have two type of photoreceptor (are red-green colour blind), but a few groups, including humans have regained a third. The typical vertebrate has 4 or more photoreceptors (red, green, blue and NUV).
The extreme among animals occurs among mantis shrimp, which have 12 to 16 types of colour receptor.
There are cryptic species complexes of 2 or more species among crickets where the easiest way of distinguishing the species is by the song - a 2017 paper recognised another 3 species in the Ducetia japonica group in this way.
Vampire bats are named after vampires, not vice versa. Vampire bats are neotropical (native to Central and South America). When haematophagous (blood eating) bats were discovered there the vampire name was transferred to them. There is also a vampire finch in the Galapagos Islands, but that is much less specialised than that the bats.
