Malachius bipustulatus - Male antenna w. excitators The males of Malachite beetles (Malachiidae) carry excitatory glands (&quot;excitators&quot;) on their body - special organs that attract females. In the various genera these excitators are located at different positions on the body. In Malachius the excitators are placed on the first antenna segments, making it easy to recognize males of Malachius by these conspicuous protuberances.<br />

Malachius bipustulatus - Male antenna w. excitators

The males of Malachite beetles (Malachiidae) carry excitatory glands ("excitators") on their body - special organs that attract females. In the various genera these excitators are located at different positions on the body. In Malachius the excitators are placed on the first antenna segments, making it easy to recognize males of Malachius by these conspicuous protuberances.
An example of excitators on the tip of the fore wings can be seen here:

  1. Neat! I had never heard of excitatory glands before. Posted 2 months ago
    1. Another strange phenomena :o) Here is an image of a female Clanoptilus elegans going wild on the excitators at the tip of the elytra of her mate ... strange stuff ... *rolleyes*

      1. I couldn't get that link to work, so I googled, "female Clanoptilus elegans going wild on the excitators" and the search results were all videos of "girls gone wild", which I guess is accurate in a way. Posted one month ago

''Malachius bipustulatus'', the malachite beetle, is a species of soft-winged flower beetles belonging to the family Melyridae subfamily Malachiinae.

The body is 5–7 millimetres long, the head and pronotum are brownish, while elytrae are shining metallic green with a bright red spot at the end. Along the sides of the abdomen this species has a peculiar structure with orange poaches.

These beetles mainly inhabit meadows at low altitudes. During the day they stay on herbs and.. more
