the insect 1
the insect 1  

the insect 2
the insect 2  
Hi, i'm Zulaiha and i live in Jordan.
starting from this springs, there's one species of insect appeared that i haven't encountered before. it is very tiny, and when it bites, it left red marks and the itchiness stays for days. it bothers us a lot as it is so itchy that we can't stop ourselves from scratching it till it bleeds.

thank you for spending your time to answer my question.

Answer
Dear Zulaiha - This is a sand fly (Diptera: Psychodidae); it looks like one in the genus Phlebotomus  - see http://tinyurl.com/gv5vwvb for an example. You should take every precaution to avoid being bitten by these insects, as they can vector the parasitic disease leishmaniasis - see http://tinyurl.com/ha4qdsr for details.
Hope this helps,
Saugy

Expertise

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.

Ten years as a civilian analyst for the Department of Defense, primarily on distribution of vector-borne diseases worldwide. Limited experience on surveillance of agricultural insects in North Dakota and Indiana.
