Kajang - Anax guttatus

Egg Laying of Anax guttatus

My field experience tells me that Anax guttatus performs oviposition from late morning to mid day in sunny day. The photo below shows an act of egg laying of a female Anax guttatus at a pond around 10.30 am.

Egg Laying of Ischnura senegalensis

I have seen a few time the egg laying of Ischnura senegalensis. I notice that the female of I. senegalensis performs egg-laying without the presence of the male.

Mating Between Two Species: Diplocodes trivialis-Diplacodes nebulosa

Mating Between Two Species: Diplocodes trivialis-Diplacodes nebulosa

I spotted a tandem pair between two Diplacodes species - Diplacodes trivialis (male) and Diplacodes nebulosa. Diplacodes trvialis (hw = 23 mm) is normal much larger than Diplacodes nebulosa (hw = 19 mm). However, the population of Diplacodes trvialis at a site in Kajang 2 is much smaller in size (hw = 17-19 mm). The below photo shows a small-sized male (blue colour) Diplacodes trivialis in tandem with a female Diplacodes nebulosa.
