Diffusers in general are not really about putting an opaque surface between the flash and the subject. They are an attempt to make the light source bigger in relation to the subject (a flash umbrella is a good example). If the llght source is larger the light comes in from wider angles and produces a softer - more gentle light. When using an umbrella or soft box for portraits, if you want softer light you make the distance between subject and light smaller - for harsher/harder light move light further away.
To sum up - for softer light - make distance between light and subject smaller - make light source larger by using a light modifier (diffuser in your case.)
For the insect shots it makes a difference (not huge but it is noticed) but depends on how close you get the flash to the subject (closer the better).
Reduce reflections yes - eliminate no. As I said before dial the flash back a little and if you have to increase exposure in post processing.
If you cannot find one for your flash - I guess get the cheapest one and hope  I have a Nissin flash and a Yongnuo flash - my diffuser fits both.
Edit: I found this for £5.49 from China. It may fit or if not you can resell on eBay http://www.ebay.co.uk/itm/Profession...MAAOSwXY5ZVc~l
Or here for £5.88 for a few canon flashes - not sure if yours is similar size - but a good chance. http://www.ebay.ie/itm/Professional-...IAAOSwIQdZJUbM
Here is a video on hard and soft light. Same thing applies for your insect shots.
