My identification up to order, suborder or family level: 1) Hymenoptera Apocrita Aculeata Sphecidae; 2) Isoptera; 3) Lepidoptera Lycaenidae; 4) Orthoptera Caelifera.

Rinaldo Nicoli

Thank you for given family level identified....

It is likely that someone else is able to say more; in every case it would be useful to indicate the region (regions) in which the photographs were taken.

Rinaldo Nicoli

We need to know where they come from, and if you could give us an idea of the size, it could help !

Picture No. 2 is Termite

I agree with Rinaldo's identification. For the Sphecid wasp, I think we may suggest a genus like Sphex, preferably to Ammophila. I agree about the three others, and share the other comments, having the geographical origin would help. For the Lycaenidae butterfly, having a view of the other side of the wings would be great (if you have it).

Picture N°4 : similar images found on the web,  identified as  "Painted Grasshopper (Poekilocerus pictus)". I'm not able to confirm this, it's just a clue !!!

Bernard Bal likely grasshopper i understood. but this species diffrent.....i am asking give exact names....

I told you it was similar ! Why do you think it's different ?

In order to give "exact name", we need to know where the specimen come from... The genus is probably good, Try to know how many species are possible in the area, and what make them different...

I know the french fauna (and I'm quite sure this one doesn't belong to this fauna)

1. The butterfly is Tarucus nara (Lepidoptera: Lycaenidae) https://www.flickr.com/photos/milindsshutterbug/7831825282

2.  The grasshopper is Poekilocerus pictus (Orthoptera: Acriididae) a female with shorter wings http://sp.depositphotos.com/stock-photos/poekilocerus-pictus.html

3. The wasp is Sphex sericus (Hymenoptera:Sphecidae)

Region of collecting and habitat characteristics are very important for this identification!

I agree - collection data data is very important. From the university and the name of the person submitting the question - South Asia, but this is a big area. Some preliminary guesses. 

1. This is a fly, Diptera, that is mimicking a wasp and doing a very good job at it - pretty cool but to get to family and beyond I will need some help.

2. These are worker termites, I think in the family Termitidae.

3. A butterfly in the family Lycaenidae, the hairstreaks.

4. This is a grasshopper. I cannot be sure of the family but my guess is Romaleidae but it is also possibly in the Acrididae, subfamily Gomphocerinae, especially because of the slanted face.

Nice photographs but some of the important identifying characteristics cannot be well seen for more complete determinations 

Thank you clifford B kelli....ya ypur guessing correct....i am also trying identification.....

last one is Poekilocerus pictus

Kingdom: Animalia

Phylum: Arthropoda

Class: Insecta

Order: Orthoptera

Family: Pyrgomorphidae

Genus: Poekilocerus

Species: P. pictus

Fig. 1  bees

Fig.2 termits

Fig. 3 Tarcus sp. Lycaenidae

Fig. Pyrgomorphinae

@Cliff: What makes you certain first one is a fly?!? I do not know any fly family with such weird celled wing veins... and also look on the face: it seems to have some real mandibles... I would go here for some kind of Hymenoptera....

First picture is it a bee (Hymenoptera) because of its venation of forewing

@Yefremova & @Keil

The Hymenopteran has already been determined positively to the Family Sphecidae and most likely genus Sphex. But as others have already stated, it would be incredibly helpful if we knew WHERE they were collected, that information has yet to be revealed.

I already have three species correctly identified :

1. Sphex sericus (Hymenoptera:Sphecidae)

2. Termites

3. Tarucus nara (Lepidoptera: Lycaenidae)

4. Poekilocerus pictus (Orthoptera: Acriididae)

Please help me: I do not understand, why here in the "scientific" Research Gate there is mostly, not only here in this question, asked for the determination of an animal or plant without any additional informations like lokation, size, date and so on? In most of the other appropriate fora this is a "no go".  

I think, in a scientific forum like Research Gate, it should be usual to add relevant additional data. Otherwise this is waste of time for anyone who is willing to help. It is difficult enough to determine a species only by photo. 

So there is benefit for both sides! No gamble play but scientific information.

@ Luis Miguel: I know, you don't want to give wildlife trafickers data for rare species and I agree with you. The data of rare species should be handled with special care.

I agree with Rudolf. Paradoxically, this is on RG that identification requests are the less "rigorously scientific". I think it is easily explained by the fact that this is not a specialized forum, and many people asking for IDs have no clue what systematics/taxonomy is.

I can't blame people for not providing info related to their ID resquests, because when I didn't know myself what taxonomy was, nor how huge the world of insects was, I was doing the same mistake. I just thought "this butterfly is certainly unique and easy to determine" and was certain that a simple picture was enough to do it. Of course it is wrong, and a wide majority of insects can't be determined with such pictures and without additional information.

But unless people were born knowing everything about systematics, we will always have requests like this.

I agree also with you, Vincent, and I didn't want to blame anybody!

Yes, I agree with Vincent and Rudolf. Is very difficult to ID a species without data of location and information of habitat of the specimen, speciallly if the person who posted the photos is not willing to cooperate giving the information,  despite that many of us requested the information many times.

Mr. Luis Miguel Constantino......we  are taking images from Andhra Pradesh in India....District of Kadapa....This 4 Images taking...18-10-2013 dated this images taken my cam.(Sri Krishnadevaraya University)....am also working plant taxonomy....field oriented...work..collections specimens. 4 yrs experience in (Andaman & Andhrapradesh) covered areas...Thank you for Identifications and given suggestion. 4 species identified completed...thank u for given ur valuble suggestions.

Thank you Chennakesavulu for your answer. This was the information and data we were waiting. Despite that I did not know the localities I was able to identify the species assuming they were from India.

Regards,

Luis Miguel

Dear Luis Miguel....Last 2 days i am not seeing RG Gate because ........thank u for cooperaion....

4th photo is of Poekilocerus sp.

The 3rd photo is a butterfly (Lepidoptera) of the Lycaenidae family. If it is a male, it would be probably useful to dissect its genitalia to know the genus and species!

The fourth picture seems to match Poekilocerus pictus (Fabricius, 1775) a Pyrgomorphidae
