Pear Slug

Caliroa cerasi

Habitat:

Backyard

Notes:

The pear sawfly, which is actually a wasp, is a common pest on pear, cherry, and hawthorn. The slug-like appearance of the larval stage has prompted this insect to also be referred to as the pear or cherry slug. Although cherry and pear are the preferred hosts, the pear sawfly will also attack plum, buttonbrush, Juneberry, mountain ash, cotoneaster and quince. On fruit trees which are treated for other pests, the pear sawfly is rarely a problem, but in untreated situations the entire tree may be defoliated.

yes, excellent plan! :)

it was welcoming you! :) don't forget to take some photos and show those great french insects to the world, too! :)

Ok we are not in a rush! We use the one in Flickr and try to follow the spottings that come here as much as possible so we don't miss the sawflies and wasps.

Thank you, already found a crazy footed shield bug on my window :)

I was talking to someone who is responsible for missions, and she told me that they request that only spottings within that radius are added, yes, it is possible to add spottings from all around the world, but it is creator's duty to control and delete spottings that are not within that radius.
So I will respect their request :) and wait for some changes :)

P.S. she told me that maybe (but only maybe) there will be a global wasp mission soon :)

I wish you great spottings in France! :)

Ioannis, thank you for the information! I know they are working on improving the application so I hope it will be soon. It's also possible to make the mission and add your spotting to it even though it's not in the included radius.

Btw, just moved to France so we should start making some missions only for french wildlife. It's a huge country so would be nice to have its own mission so it's easier to study the species in France.

Hello. First to say: very nice spot, I really thought it was a slug!
About missions: I saw some comments from one NoahRanger on the support chat, saying there would be a rewrite of the code about missions because of some problems with the current implementation but with no schedule. I don't remember who the Ranger was to ask him details but he/she said that with the new implementation the limits could be defined by frontiers and not only by distance. Probably you can ask in the support chat to know more.
I noticed that when I look for local missions in France I find nothing, but I can add my butterflies to the "European butterfly" mission which is not global but contains spots from Portugal to Croatia and from Italy to Island, so far beyond the 482km radius! http://www.projectnoah.org/missions/8...
I don't know how this is compatible with the fact that this is not a global mission but it could be a solution to your problem.

FaredinAliyevski
FaredinAliyevski 10 years ago

Yes exactly on that tinny area of course you are the only one because we don't have many people in europe. In denmark I am the only that is active for a long. Doesn't matter, it's their lost we do it in flickr :)

Sintija Valucka

So first of all I have to create a local mission (people can add their spottings within the 482 km radius) and if the mission becomes popular I can ask them to consider making it global, but the problem is that within 842 km radius there is only me :( (maybe not only :D , but at least there aren't active spotters) and I don't think that they will consider a mission popular if there's only one person it it... :(
842 km is really not so much..
So I'm not creating the mission.
but I did create a group "Sawflies and wasps of the world" on Flickr! :)
if you decide to join Flickr, you are very welcome to join this group, too! :)

Let's see how fast they will be with answering! :)

Flickr is great! :)
And they really have lovely grubs :) but they need many more photos!

FaredinAliyevski
FaredinAliyevski 10 years ago

Nice, you are fast! :)

I haven't uploaded my photos anywhere apart from here and facebook but have been thinking of flicker so should become a part of that group. They have nice 'grubs' :)

Sintija Valucka
Sintija Valucka 10 years ago

Yes, both together would be nice :)
I asked them about global missions, so now I'm waiting for the answer! ;)

in the mean time I found a sawfly larvae group on Flickr :) do you upload your phots on flickr, too?
There's the group http://www.flickr.com/groups/sawflylarva...
and someone has uploaded there a picture of this pear slug, too! :)

FaredinAliyevski
FaredinAliyevski 10 years ago

I think wasps should be included as well but you are the creator so as you wish :). Sawflies and Wasps look kind of similar so they could go together and also we don't get many spottings of sawflies so better to include them together.

Sintija Valucka
Sintija Valucka 10 years ago

If sawflies and wasps, people could add all those interesting digger wasps and gall wasps, too :)

Sintija Valucka
Sintija Valucka 10 years ago

I'm ready to create one! :)
So - only for sawflies and their grubs? or you want wasps in it, too?

FaredinAliyevski
FaredinAliyevski 10 years ago

I don't know how that is decided but they better do it since we really need a mission for wasps if it already doesn't exist.

Sintija Valucka
Sintija Valucka 10 years ago

yes, unfortunately, I am aware of that! :)

and how do they decide that? :)

FaredinAliyevski
FaredinAliyevski 10 years ago

We will become professionals but not in everything, just in certain things :).

Missions are easy to create but we need it to become a global mission and that's something the coordinators decide.

Sintija Valucka
Sintija Valucka 10 years ago

Professionals - sounds great! :) Actually, that is what I'm amaing at :)) I want to know all the insects (and also birds, and fungi, and all the other organisms) :)
I know I won't achieve this goal, but at least I will die trying :)

Now because of the weather I can find barely any insect (including sawfly grubs) :(
but the next year will be a good one :)

and yes, sawflies deserve their own mission! :)
Tomorrow I will read about the creation of missions, now it's a bit too late :)

FaredinAliyevski
FaredinAliyevski 10 years ago

Hahah, and I'm working on Neurogenetics in Drosophila so these organisms are also my hobby but of course if we keep learning and exploring our hobbies after some time we will become professionals :).

Yes, we need more of these crazy creatures, I think adults are easier to find but we should try and make a mission at some point :).

Sintija Valucka
Sintija Valucka 10 years ago

haha, I am a biologist, but I'm studying microbiology :D
insects and other big organisms are only my hobby :) and I really got puzzled with this one! :))
and, yes, we should!!! Sawflies are really amazing!!! and there should be a sawfly mission here on PN! :) So people could add their great findings :))
and we also have to find more and more intersting grubs and grown-ups, too! :)

Congratulations with the first spotting!! :)

FaredinAliyevski 10 years ago

Thank you martinl! We are both biologists so we have some knowledge I guess but had not seen this one before so got a bit puzzled. I hope I will always find something I have no idea what it is :). Sinitja, we should start studying sawflies :). This is the first spoting of this species in PN :)

Sintija Valucka
Sintija Valucka 10 years ago

Thank you! :)
Welcome to English in my case :)
In my language we have only one word for all of these :D

The term 'slug' is unfortunate. Sawfly (wasp) grubs usually look like this http://www.projectnoah.org/spottings/383... . Hymenoptera (ant,bee wasp,sawfly) and coleoptera (beetle) larvae are called grubs. Diptera (fly) larvae are usually called maggots. Lepidoptera (butterfly, moth) larvae are called caterpillars. Sometimes unusual moth caterpillars are called slugs too http://www.projectnoah.org/spottings/380...
Welcome to biology.

Sintija Valucka
Sintija Valucka 10 years ago

It looks like sawflies have the craziest larvae!! They are so different and so weird! :)

FaredinAliyevski
FaredinAliyevski 10 years ago

martinl, thanks a lot! I wish my garden was a rain forest :). To me looked to slimy to be a caterpillar but it's amazing that actually this is an insect. I guess it's one of the craziest transformations.

Sintija Valucka
Sintija Valucka 10 years ago

I had two ideas - one was a leech :D (like those who live on trees in rain forests (as if your garden was a rain forest :D ...)) and the second was a caterpillar :)
Great that martinl, knew what it is! :)
slug as an option didn't came into my mind...
