Two-spotted Longhorn Bee (Melissodes bimaculatus)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Two-spotted Longhorn Bee.

 Updated: 2/7/2019; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




Two pale spots near the tip of the abdomen are useful identifiers for the Two-spotted Longhorn Bee.



Male Longhorn Bees have antennae that are about twice as long as usual. The genus has at least 100 different species and they vary in coloration. This particular species has two light spots near the end of its abdomen that stand out against its black body. The hind legs have long, yellow hairs on them, making them easier to tell apart from other medium-sized bees. The dense and expansive covering of hair may look like pollen dust at first glance. These long hairs help trap pollen grains from the flowers they visit.

It is believed that females collect pollen grains for future consumption by newly hatched bee larvae. Longhorn Bees are quite common throughout North America. In the spring and early summer, they can be found collecting pollen from a variety of blooming flowers, especially in agricultural fields. Look for them on the blossoms of coneflowers, asters, mallows, and legumes. Despite their ubiquity, few species have been studied well, so little is known about them.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.




Ant, Bee, and Wasp Anatomy
Graphic showing basic anatomy of both a bee and an ant insect
1
Antennae: Ants and Bees both have a pair of antennae on the head that senses their surroundings.
2
Head: The head contains the insect's compound eyes, antennae, and mandibles.
3
Thorax: Contains various vital parts such as the aorta and nervous system.
4
Abdomen: Contains various organs including the heart, gut, venom glands, and anus.
5
Legs: Ants and Bees have three pairs of legs attached to the thorax (center-body section).
NOTE: Ants, Bees and Wasps are part of the Hymenoptera order because they share many similarities.
