There have been mentions of sightings of these beetles in many parts of the world, like Russia, Australia, the North and South Islands of New Zealand, North America, South America, Europe, or Asia.

What is a false blister beetle's habitat?

Mostly these species can occur around the coastline of many countries. There have been records of these beetles living in tropical areas and in moist forest areas. Their nature changes according to the geographical range and climate change of habitats. The adults can be seen around flowers or foliage, and many living in a tropical range of habitat are attracted to lights, so at night a large number of them can be seen flying around lights. The larvae are mainly seen living on moist logs or decaying wood, roots and stumps of conifers, driftwood, and hardwoods of riverbanks or beaches.

Who do false blister beetles live with?

Among the 1500 species of beetles, not all show uniform characteristics. Some species can be seen living solitary lives, while some can be seen in aggregations.

How long does a false blister beetle live?

The exact lifespan of the beetles on average is not known. Some adult beetles, like the wharf borer, live for almost a year or so. Most beetle species of the family Oedemeridae are known to live more or less a year, as their reproductive cycle suggests that many among the species lay a clutch of eggs once a year.

How do they reproduce?

The reproductive cycle and life cycle are not known for many among the 1500 species. The few species that we are familiar with, their life cycle occurs in a yearly manner. Sometimes, the breeding cycle occurs when some flowers blossom around them. The male and female adults of both gender feed on flower pollen, so attracting the other gender occurs easily for the beetles. The only condition for the females is that they don't mate until they have eaten a gut full of pollen. The beetles are known to mate on the flower heads they were feeding on. The females digest the pollen grains inside their gut and use them to produce eggs. The females lay their eggs on the bark of nearby trees or plants, on decaying or wet woods, debris, driftwood, and sometimes, even can be seen making burrows in wet soil. When these eggs hatch, the larvae drop on the ground from the plants of the woods. After the larvae drop on the ground, it's assumed that they feed on rhizomes and rootlets. These larvae grow in wet soil under the trees and go through pupation there. When beetles grow into adults and come out of the pupae, they continue with this life cycle.

What is their conservation status?

Not all among the family Oedemeridae have been listed in the International Union for Conservation of Nature Red List. Some among the species have been listed as Least Concern, like the Wharf Borer (Nacerdes melanura), Anogcodes fulvicollis, or Ischnomera xanthoderes. Some among them have been listed as Near Threatened, like the Nacerdes hesperica or the Sparedrus lencinae. The biggest threat the species faces is habitat loss due to the destruction of forests.
